SOF SoundWire: Improve dmic detection

[GitHub pull_request - edited]

alsa-project/alsa-ucm-conf pull request #75 was edited from plbossart:

DMIC support seems incomplete for HDaudio (not handling all possibilities for cfg-dmics) and missing completely for SoundWire.

This is an untested draft just to get UCM3 feedback from @perexg and tests from @aigilea on an HP Spectre x360 device.

Edit: adding @kv2019i @RanderWang @bardliao and @libinyang for reviews.
