Bug description:
  [Impact]
  We have backported the amd renoir audio driver to oem-5.6 and focal
  kernel, recently we found if the dmic is working and we suspend and
  resume, the dmic can't record the sound after resume.

  [Fix]
  After resuming, the driver needs to restore 2 more registers, then the
  dmic could record the sound.

  [Test Case]
  Boot the kernel with this patch, open the sound-setting and run suspend
  and resume, then use arecord to record the sound, verify the sound is
  successfully recorded by aplaying it.

  [Regression Risk]
  Low, this patch is verified on the amd renoir machine, and this patch
  got ack from AMD engineer.
