Bug description:
[Impact]
So far, if we want the sof driver to work, we need to blacklist
snd_hda_intel.ko, but on some paltforms with nv hdmi or amd hdmi,
we need these two driver co-exist.
[Fix]
Intel sent the patches to fix this issue, although it is not merged yet,
but I guess they will pass the review and be merged. So i backported them
first.
[Test Case]
remove snd_hda_intel.ko from blacklist, the two drivers (sof and hda)
worked well.
[Regression Risk]
Low. We already tested these patches on some Dell machines. and comunity
including endlessm and goole all tested these patches.
