[PATCH 2/2] arm64: mediatek: mt8195-cherry: Introduce the MT8195 Dojo Chromebook

[AngeloGioacchino Del Regno]

Add a devicetree for the Cherry Dojo (HP Chromebook x360 13b-ca0002sa)
convertible type machine.

Differences with the already supported Tomato machines include:
 - Different speaker amplifiers (Dual MAX98380, one per channel)
 - I2C Touchscreen is on a different address (though still a HID device)
 - Has NVMe storage on the PCIe0 controller
 - Slightly different keyboard top row keymap
