[SRU][Focal][PATCH 0/3] Audio fails to initialize on icl machines

[Hui Wang]

BugLink: https://bugs.launchpad.net/bugs/1886341

These patches are already in the Groovy kernel and oem-5.6 kernel, so
only focal kernel needs these patchees.

[Impact]
On the machine of Lenovo IdeaPad 5 15IIL05, the audio doesn't work,
checking the dmesg, I found the audio driver fails to initialize
because it fails on i915 audio codec probe.

[Fix]
backport 3 patches from mainline kernel, move the i915 audio codec
init earlier.

[Test Case]
Boot the kernel with these 3 patches, check dmesg, there is no
i915 audio codec probe error anymore, and audio driver initializes
successfully, and input and output audio devices all work.

[Regression Risk]
Low, already tested these 3 patches on a couple of LENOVO dmic
machines (cnl and cml machines), all work as well as before.
