Urgh. I've accidentally released linux-firmware to focal without
verification, and without waiting for the groovy task to be done. Hui,
can you please test this for focal and groovy? Thanks.

Bug description:
  [Impact]
  In the OEM project, we have a new TGL-H soundwire machine, with
  the current oem-5.10 kernel, the audio can't work.

  [Fix]
  Backport 6 patches from Intel thesofproject kernel.

  [Test]
  Put the testing sof-tgl-h.ri in the /lib/firmware/intel/sof,
  boot the patched kernel, we could see speakers and microphone
  from gnome-setting, and they all work well.

  
  [Where problems could occur]
  The patches changed soundwire machine driver, it is possible
  to make the audio on old soundwire machines not work anymore.
  But we tested the patches on TGL-U and cml soundwire machines,
  all worked well.
