ASoC: SOF: Make sof_widget_setup/free IPC agnostic
Add 3 new topology IPC ops for widget_setup, widget_free and dai_config
in order to make the pipeline management code IPC agnostic and implement
the ops for IPC3.

Use the newly introduced tplg dai_config op to configure the DAI during
BE DAI hw_params and hw_free.

Also, in preparation for IPC4, modify BE hw_params callback to skip
setting up the DAI widget. All widgets will be set up during FW
hw_params and the DAI_CONFIG IPC should be sent only if the widget
use_count is > 0. With setting up/freeing removed from the BE hw_params,
remove the configured flag as it is no longer needed.

ASoC: SOF: topology: Make control parsing IPC agnostic
Make the control parser in topology IPC agnostic by introducing 2 new
topology IPC ops, control_setup and control_free. These ops handle
setting up/freeing the control data in the IPC format based on the IPC
version.

Along with this, modify the struct snd_sof_control to remove the
IPC-specific field, control_data and replace it with the void pointer to
ipc_control_data. Also, add a few new fields to store all the
information parsed from topology.

Finally, define and set the control setup/free ops for IPC3.

ASoC: SOF: add support for dynamic pipelines with multi-core
This patch adds support for dynamic pipelines with multi-core
by using the platform-specific core_get/put() ops to
power up/down a core when a widget is set up/freed.

Along with this, a few redundant functions are removed:
1. sof_pipeline_core_enable() is no longer needed as the
pipeline core will be set up when the pipeline widget
is set up
2. sof_core_enable() is replaced with snd_sof_core_get()
4. core_power_up/down() DSP ops are deprecated and replaced with
core get/put ops.
5. Core power down in sof_widget_unload() during topology
removal is also removed as it is not really needed. For dynamic
pipelines, the cores will be powered off when they are not used.
For static pipelines, the cores will be powered off in the device
remove callback.

ASoC: SOF: Introduce fragment elapsed notification API
This patch prepares the introduction of the compress API with SOF.

After each fragment is accepted by the DSP we need to inform
the userspace applications that they can send the next fragment.
This is done via snd_compr_fragment_elapsed.

Similar with the PCM case, in order to avoid sending an IPC before
the previous IPC is handled we need to schedule a delayed work to
call snd_compr_fragment_elapsed().

See snd_sof_pcm_period_elapsed.

To sum up this patch offers the following API to SOF code:
	* snd_sof_compr_init_elapsed_work
	* snd_sof_compr_fragment_elapsed

Note that implementation for compressed function is in a new file
selected via CONFIG_SND_SOC_SOF_COMPRESS invisible config option.
This option is automatically selected for platforms that support
the compress interface. For now only i.MX8 platforms support this.

For symmetry we introduce snd_sof_pcm_init_elapsed_work to setup
the work struct for PCM case.

ASoC: SOF: Add support for dynamic pipelines
Add support for dynamic pipelines by modifying the PCM
hw_params ioctl implementation to determine the widgets
required for a PCM stream by querying the list of
connected DAPM widgets. This list is saved as part of
snd_sof_pcm_stream struct and will be used to setup the widgets.

The sof_widget_list_setup/free routines setup and free connected
DAPM widgets when a PCM is opened/closed. These routines accept
a list of connected DAPM widgets as input and determine the SOF
widgets, their corresponding pipeline widgets and connections
between them that need to be setup before the PCM is triggered.

Please note that the dynamic pipeline feature will only be enabled
for those pipelines whose dynamic_pipeline_widget flag is set in
topologies. Add a new token called SOF_TKN_SCHED_DYNAMIC_PIPELINE
that when set in topology will be applied to the
dynamic_pipeline_widget flag of the pipeline widget.

ASoC: SOF: Intel: hda: make sure DAI widget is set up before IPC
With the implementation of the dynamic pipeline feature, widgets
will only be setup when a PCM is opened during the
hw_params ioctl. The BE hw_params callback is responsible for
sending the DAI_CONFIG for the DAI widgets in the DSP.
With dynamic pipelines, the DAI widgets will need to set up
first before sending the DAI_CONFIG IPC in the BE hw_params.

Update the BE hw_params/hw_free callbacks for all ALH, HDA and SSP
DAIs to set up/free the DAI widget before/after DAI_CONFIG IPC.

ASoC: SOF: topology: Add new token for dynamic pipeline
Today, we set up all widgets required for all PCM streams
at the time of topology parsing even if they are not
used. An optimization would be to only set up the widgets
required for currently active PCM streams. This would give
the FW the opportunity to power gate unused memory blocks,
thereby saving power.

For dynamic pipelines, the widgets in the connected DAPM path
for each PCM will need to be set up at runtime. This patch
introduces a new token, DYNAMIC_PIPELINE, for scheduler type
widgets that indicate whether a pipeline should be set up
statically during topology load or at runtime when the PCM is
opened. Introduce a new field called dynamic_pipeline_widget
in struct snd_sof_widget to save the value of the parsed token.

The token is set only for the pipeline (scheduler type)
widget and must be propagated to all widgets in the same
pipeline during topology load. Introduce another field called
pipe_widget in struct snd_sof_widget that saves the pointer to
the scheduler widget with the same pipeline ID as that of the
widget. This field is populated when the pipeline completion
callback is invoked during topology loading.

ASoC: SOF: Handle control change notification from firmware
If the value/data associated with a control changes in SOF it will send a
notification (SOF_IPC_GLB_COMP_MSG with SOF_IPC_COMP_GET_VALUE/DATA).

We have support for binary volatile control type, but we might have
features where enum/switch/volume changes. Re-implementing everything as
volatile as well would be not much of a gain for several reasons:
- volatile controls would do an IPC all the time, regardless if there is a
  need or not.
- We still don't have notification which forces userspace to continuously
  poll.

When such notification arrives we use snd_ctl_notify_one() to signal
userspace about the change.

The kernel is prepared for two types of notification:
- the notification carries the new data for the control (num_elems != 0)
The new value/data is copied to the control's local data

- blank message about a change
The new flag for the scontrol (comp_data_dirty) is set and when next
time user space reads the value via the kcontrol's get callback we will
refresh the control's local data from the firmware.

ASoC: SOF: control: override volume info callback
ASoC dapm controls currently don't support more than 2 channels. This is
a problem for SOF-based devices where individual volume control cannot
be provided on the 4 DMIC input path.

If we want to provide controls for more than 2 channels, this patch
suggests a simple solution based on an override of the info callback.
For example, in the case with 4 channel DMIC PGAs, a sof_info callback
would be used. Mono and stereo cases will keep using the existing dapm
info callback.

A longer-term solution would be to remove the limits to 2 channels in
ASoC/DAPM/topology. This is a topic Intel is currently looking into,
e.g. by removing the use of 'reg' and 'rreg' fields and use arrays
instead. Such changes will be rather intrusive and touch multiple codec
and platform drivers. Removing restrictions is the right thing to do,
but this will need to be done in steps with lots of validation.

ASoC: SOF: support topology components on secondary cores
Currently SOF supports running pipelines on secondary DSP cores in a
limited way. This patch represents the next step in SOF multi-core DSP
support, it adds checks for core ID to individual topology components.
It takes care to power up all the requested cores. More advanced DSP
core power management should be added in the future.
