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 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.

Changes since v1:
- Reorder SKU numbers in descending order.
- Mark missing components as disabled instead of deleting the node
- Switched to interrupts-extended in touchscreen nodes
- Dropped reset-gpios from touchscreen nodes
- Drop status = "okay", which is the default
