arm64: dts: mediatek: Add MT8186 Krabby platform based Tentacruel / Tentacool 



Tentacruel and Tentacool are MT8186 based Chromebooks based on the
Krabby design.

Tentacruel, also known as the ASUS Chromebook CM14 Flip CM1402F, is a
convertible device with touchscreen and stylus.

Tentacool, also known as the ASUS Chromebook CM14 CM1402C, is a laptop
device. It does not have a touchscreen or stylus.

The two devices both have two variants. The difference is a second
source trackpad controller that shares the same address as the original,
but is incompatible.

The extra SKU IDs for the Tentacruel devices map to different sensor
components attached to the Embedded Controller. These are not visible
to the main processor.
