Skitty is MT8186 based Chromebook based on the Krabby design.

Skitty also known as the HP Chromebook G1m 11 inch. The device is
a clamshell laptop with an optional touchscreen and keyboard.

The SKU IDs of the Skitty devices map to different touchscreen and
keyboard.

This patch depends on patch "dt-bindings: arm: mediatek: Add MT8186 Skitty"
