caebea04b9 ASoC: SOF: Intel: add hw specific PCM constraints 
Part of PCM constraints are set based on DSP topology, but rest
should be set based on hardware capabilities. Add PCM constraints
for Intel platforms:

- Add constraint for the period count to be integer. This avoids
  wrap-arounds of the DMA circular buffer in middle of a period.

- Align period size to dword/32bit as per HDA spec.

Both constraints are aligned with current implementation in snd-hda-intel
driver.

49d7948ed1 ASoC: SOF: Intel: Expose SDnFMT helpers 
Hda stream is setup in similar fashion for compress as it is for pcm
operations. To reuse existing code in compress path, expose SDnFMT
helper routines.

ee1e79b72e ASoC: SOF: partition audio-related parts from SOF core 
Move all the audio-specific code in the core,
audio-specific logic in the top-level PM callbacks
and the core header files into a separate file
(sof-audio.*) in preparation for adding an
audio client device.

In the process of moving all structure definitions
for widget, routes, pcm's etc, the snd_sof_dev
member in all these structs is replaced with
the snd_soc_component member. Also, use the component
device instead of the snd_sof_dev device wherever
possible in the PCM component driver,
control IO functions and the topology parser as the
component device will be moved over to the client
device later on.
