Subject: [PATCH v3 5/6] ASoC: amd: ps: Adjust the gain for PDM DMIC

No issues have been reported yet for DMIC audio level on ps platforms,
but as problems were found both on YC (Rembrandt) and Renoir based
designs it's very likely they happen on ps too.

Increase the PDM gain to solve this problem.
