Add entries for MT8186 based Tentacruel / Tentacool Chromebooks. The two
are based on the same board design: the former is a convertible device
with a touchscreen, stylus, and some extra buttons; the latter is a
clamshell device and lacks these additional features.

The two devices both have two variants. The difference is a second
source touchpad 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.
