ucm2: Add support for MT8195 Cherry Tomato Chromebook with SOF

Add support for the Acer Chromebook Spin 513 CP513-2H, powered
by MediaTek Kompanio 1380 (MT8195) with a HiFi 4 Audio DSP running
SoundOpenFirmware.
This machine uses MT6359 PMIC, with RT1019 and RT5682 as headphones
and speaker codecs/amps.

This configuration has been successfully tested on Debian 11
with PipeWire 0.3.56 + wireplumber.

Fixes: #213
