UCM file required for Multiple sound card scenario for Renoir APU

alsa-project/alsa-ucm-conf issue #30 was opened from VijendarReddy:

We recently upstreamed PDM Driver for Renoir APU.

Renoir APU platform has Onboard DMIC + Southbridge AZ (HD Audio Endpoint) support. When External Mic connected, Device switching should happen from Internal DMIC to external Mic.

Need UCM file to support Multiple sound cards for Renoir APU.
