Add a simple "fallback" machine driver that can be used to enable SOF
on boards with no codec device. This machine driver can also be forced
for debug/development.

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.

The Sound Open Firmware driver core is a generic architecture
independent layer that allows SOF to be used on many different 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.

hdac_bus library.
In some cases, we want to initialize hda bus without this hdac_bus
library(e.g. for non-HDA I2S only usuage on Intel Skylake+ platforms),
where we will do hdac bus non-HDA-only implementation in BSD license.
When we want to add hda link support(GPL) in this implementation, we
need reuse this process_unsol_events(), so export it is better solution
comparing to implement it again.

A kernel oops happens on an error case (usual missing BE mixer
configuration required by Intel SST driver). Git bisect points to this
macro and an operator precedence issue.
for (; ((i--) >= 0) && ((dai) = rtd->codec_dais[i]);)
The initial code replaced by this macro was
while (--i >= 0) {
codec_dai = rtd->codec_dais[i];
