[PATCH v3] ASoC: amd: add DMIC support for RPL platform

[Mingyou Chen <qby140326@gmail.com>]

Add DMIC support for the AMD RPL platform. The drivers are derived on
the YC platform driver.

Signed-off-by: Mingyou Chen <qby140326@gmail.com>
---
v2:
  - Reverse ACP CONFIG PIN from 10 to 14 for rpl
  - Remove the rpl folder
v3:
  - Remove rpl configuration from Kconfig and Makefile
