All machines of the Cherry platform have a working DSP (integrated
into the MT8195 SoC), and audio support, some with a different audio
codec: specifically, some using Realtek's RT5682I and some RT5682S.

Write a configuration for all the audio bits to enable functionality.

I think we're still missing some code for SOF that implements the
machine_select() callback, plus the firmware has to be fetched from
the ChromeOS rootfs.

It might make sense to have SOF disabled for now. Removing the adsp
reference and the overriding dai-link entry from the sound node
should do the trick.


Uhm... I think that we should either have audio, with DSP, or not have it
at all... the userspace configurations will differ, so we'd end up with
two different confs of which one will get unused and cluttering the ucm2
conf git.

At this point, I think that the most sensible option is to either omit
this commit, or keep audio disabled until the machine_select() callback
gets in...
