ASoC: SOF: Intel: use snd_sof_pcm_period_elapsed
Switch to a wrapper function which schedules the actual call of
snd_pcm_period_elapsed after the current IPC is completed.

ASoC: SOF: PCM: add period_elapsed work to fix race condition in interrupt context
The IPC implementation in SOF requires sending IPCs serially: we should
not send a new IPC command to the firmware before we get an ACK (or time
out) from firmware, and the IRQ processing is complete.

snd_pcm_period_elapsed() can be called in interrupt context before
IRQ_HANDLED is returned. When the PCM is done draining, a STOP
IPC will then be sent, which breaks the expectation that IPCs are
handled serially and leads to IPC timeouts.

This patch adds a workqueue to defer the call to snd_pcm_elapsed() after
the IRQ is handled.

ASoC: SOF: Intel: hda: set I2S slave before enabling DSP
By default, the I2S ports are configured in master mode during
DSP powerup sequences, the FS and BCLK lines will be driven on
startup, even when the topology file explicitly requires the
SSP to be slave.

This may be problematic for external components configured in
master mode who don't expect the Intel SOC/PCH to drive. Fix by
configuring the SSP as slave before the SSP outputs are enabled
to avoid this transient behavior.

When the topology file configures the SSP as clock master, the
initial slave configuration will be overridden.

ASoC: SOF: remove redundant null checks of dai
Currently there are two null checks of pointer dai in function
sof_connect_dai_widget and yet there is no null check of dai
at the end of the function when checking !dai->name.  The latter
would be a null pointer deference if dai is null (as picked up
by static analysis), however the function is only ever called
when dai is successfully allocated, so the null checks are
redundant. Clean up the code by removing the null checks.

ASoC: SOF: Add DSP firmware logger support
This patch adds support for real-time DSP logging (timestamped events
and bespoke binary data) for firmware debug. The current solution
relies on DMA transfers to system memory that is then accessed by
userspace tools such as sof-logger. For Intel platforms, two types of
DMAs are currently used (GP-DMA for Baytrail/CherryTrail and HDaudio
DMA for SKL+)

Due to historical reasons, the driver code follows the DSP firmware
conventions and refers to 'traces', but it is currently unrelated to
the Linux trace subsystem. Future solutions will include support for
more advanced hardware (e.g. MIPI Sys-T), additional formats and the
ability to enable/disable specific traces dynamically.

this should only used in engineering builds w/ debug options. This

ASoC: SOF: Add Sound Open Firmware KControl support
SOF exposes regular ALSA Kcontrols that are defined by topology. This
patch converts the Kcontrol IO to DSP IPC.

The current implementation is aligned with previous Intel solutions,
but is not optimal and can be improved:
a) for every get/put the host wakes up the DSP and generates an
IPC. The kernel should cache the values and generate an IPC only when
strictly necessary.
b) the firmware can be implemented to only instantiate the pipelines
and related control-related parts that are needed at a given time, and
power-gate the relevant SRAM blocks.

The development tasks for these two improvements has started, once
validated they will be provided in an update.

ASoC: SOF: Add Sound Open Firmware driver core
The Sound Open Firmware driver core is a generic architecture
independent layer that allows SOF to be used on many different
architectures and platforms. It abstracts DSP operations and IO
methods so that the target DSP can be an internal memory mapped or
external SPI or I2C based device. This abstraction also allows SOF to
be run on many different VMs on the same physical HW.

SOF also requires some data in ASoC PCM runtime data for looking up
SOF data during ASoC PCM operations.
