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

v2:
  - Reverse ACP CONFIG PIN from 10 to 14 for rpl
  - Remove the rpl folder
v3:
  - Remove rpl configuration from Kconfig and Makefile
v4:
  - Handle separate switch case for RPL platform (ACP Pin config)

I didn't realize there was a RPL driver upstream at this point, sorry 
about my mistake on the earlier patch.  But I do still have a concern 
with the approach you're doing considering that.  You have way too much 
stuff going on in one patch.

I feel that this should be a series with multiple patches.
1) Add support for correct pin config in YC
2) Drop RPL driver
3) Add the quirk for your system

Think it through like this - when I look over your diff for each patch 
your changelog should mention exactly what it is going in that 
individual patch.  If it's covering more than one thing it needs to be
an atomic action and justifiable to happen at once.  Otherwise split 
each thing to it's own patch.

This is important for a variety of reasons.

1) It makes the work of a reviewer a lot easier.
2) It makes bisection possible to figure out the smallest change that 
caused an issue.

This is really weird - did you mean to include this?

Please don't send new patches in reply to old patches or serieses, this
makes it harder for both people and tools to understand what is going
on - it can bury things in mailboxes and make it difficult to keep track
of what current patches are, both for the new patches and the old ones.
