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.
