Motivation for this change
Trying to get microphone working on X1 Carbon gen7, it requires Sound Open Firmware support, as it looks like all the new Intel machines will require it.
Additionally to updated alsa-lib (#83155), sof firmware files and updated kernel config enables dmic microphone support and sound in general using SOF.
I've tested those changes on kernel versions:
SOF kernel support is available from 5.2, but I suggest we leave it enabled from 5.5,
dmesg
looks scary in later versions.Archlinux also enabled SOF in their default kernel config
