[PATCH 9/9] arm64: dts: mediatek: Add MT8186 Magneton Chromebooks

Add entries for the MT8186 based Chromebooks, also collectively known
as the Lenovo IdeaPad Slim 3 Chromebook (14M868). It is also based on
the "Steelix" design. Being a laptop instead of a convertible device,
there is no touchscreen or stylus, which is similar to Rusty. However
Magneton does not have ports on the right side of the device.

Three variants are listed separately. These use different touchscreen
controllers, or lack a touchscreen altogether.
