[PATCH 0/4] MT8195 Acer Tomato - Audio support

[AngeloGioacchino Del Regno]

This series enables full support for audio, with DSP, on the Cherry
Chromebooks.
Related ALSA UCM2 configuration was already merged in its upstream
repository [1]: this is fully tested and working as-is since all of
the required fixes for MT8195 SOF drivers were picked and are present
since `next-20220908`.
