The DSP can have more than one cores. In that case the secondary
core has to be managed by the driver. This patch adds the changes
to driver infrastructure to support multiple core.
A new object skl_dsp_cores is introduced to support multiple
core. Helpers skl_dsp_get_core() skl_dsp_put_core() help to
managed the cores.
Many of the power_up/down and DSP APIs take additional argument
of core_id. The primary core, 0 is always powered up first and
then on demand second core.

Broxton DSP needs retains code loaded during runtime_pm cycles.
But it looses that on suspend cycle, so on resume we need to
download the firmware again.
This is done by adding a new flag and based on flag status, we
download the firmware.

On suspend firmware is re-initialized so resources are reset inside
firmware. Driver should also clear the firmware counters at this time.

Module params like module_id and loadable flag can be changed
in the DSP Firmware. These are kept in the firmware manifest
and driver should read these values from this manifest.
So, add support to parse the DSP firmware manifest and
read these module params.

MISCBDCGE is a new register for Misc Backbone clock gate control
which is useful to control while resetting the link and ensuring
controller is in required state so add API to control it
HW recommends that we reset with CGCTL.MISCBDCGE disabled, so add
that while doing init chip and reset sequence.

For messages which have larger payload than mailbox data, we need
to split the payload using set of messages containing mailbox
size as payload.
For sending such payload we already support LARGE_CONFIG_SET
IPCs and now to query such payload add LARGE_CONFIG_GET IPC

A module is loaded when the path consisting the module is opened.
The module binary(ies) is loaded from file system and cached in
kernel memory for future use. This is downloaded to DSP using DMA
and invoking Load module IPCs
This patch adds support for load/unload module IPCs, DMAing
modules and manging the modules

On runtime pm resume, we need to download the firmware, also on
suspend we need to ensure all the interrupts from controller and
DSP are disabled.
Also since we download the firmware on resume, we don't need to do
so on init, so remove that bit

This adds base SKL IPC library which uses common SST IPC lib.
Here we add definition for IPC types, sending and receiving IPC messages
from aDSP, handling interrupt, sending different types of messages etc
