Add support for saving and restoring DSP context in D3 to host DDR.

The suspend callback includes: suspend all pcm's stream that are running,
send CTX_SAVE ipc, drop all ipc's, release trace dma and then
power off the DSP.

And the resume callback performs the following steps: load FW, run FW,
re-initialize trace, restore pipeline, restore the kcontrol values
and finally send the ctx restore ipc to the dsp.

The streams that are suspended are resumed by the ALSA resume trigger.
If the streams are paused during system suspend, they are marked
explicitly so they can be restored during PAUSE_RELEASE.

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.

Add debugFS files that can be used to expose DSP memories and
and peripherals to userspace to assist with firmware debugging.

Since we cannot rely on debugFS, errors are logged but don't stop
execution.

When a resource cannot be read in D3, it is optionally cached on
suspend. Copying memories from IO will increase the suspend latency,
this should only used in engineering builds w/ debug options. This
part will have to be enhanced when support for D0ix states is
provided, currently only D0 and D3 are supported.

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.

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.
