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.
