Bug description:
  [Impact]
  the alsa upstream worte the ucm3 files for amd renoir audio, but to
  load the ucm3, it depends on the kernel module name, and the upstream
  ucm3 needs the name snd-xxx, so we need to backport the patches
  from mainline kernel to change the kernel module name to meet ucm3
  requirement. BTW, there are some dmic dynamically detection patches,
  we integrate them too.

  [Fix]
  Backport 1 patch from upstream.

  [Test Case]
  boot the kernel with the patch on amd renoir machines (lenovo
  machines), the audio driver works well (via command line like
  aplay or areord), then upgrade the alsa-lib and alsa-ucm-conf to
  1.2.3.2, now we could see the audio devices from gnome, and they work
  well.

  [Regression Risk]
  Low, this SRU are only specific to soc/amd/renoir, and we already
  tested on 2 lenovo machines, their audio worked as before.
