2020-11-19ASoC: SOF: Intel: add hw specific PCM constraintsKai Vehmanen1-0/+7
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.

The legacy IPC routines are only used by broadwell and baytrail modules, import them as needed and make sure other modules cannot load them.
