Bug description:
Since Bionic kernel doesn't support ICL platforms (i915), so these two
patches will not be sent to Bionic kernel.
[Impact]
On the ICL platforms, the hdmi can't work well, the audio driver
will print "azx_get_response timeout" randomly, then the whole
audio doesn't work anymore.
[Fix]
Intel provide these two fixes to us, and we tested these two
patches, it really fixed the issue.
[Test Case]
Boot and check the hdmi audio, then suspend and resume, check
the hdmi audio, all work well.
[Regression Risk]
Low, Only enable the audio PIN and enable the clock for ICL. we
tested on both ICL and non-ICL, all worked well as before.
