[v4] sof-soundwire: Add basic support for cs42l43

Commit Message

cs42l43 is a codec device, add basic support for it. Including a dual
channel DMIC input, stereo headphones, and a mono headset microphone.

Changes since v3:
 - Rebase on GitHub series
 - Add control remapping for the PDM volume/switch

Little earlier than expected, still reviewing the workings behind the
scenes but this all tests out fine. So no need to hold everything up
on my account.

Thanks,
Charles
