[PATCH] arm64: dts: mt8183: add cbas node under cros_ec

[Ikjoon Jang]

Add a 'cbas' device node for supporting tablet mode switch in
kukui devices.

Kukui platforms with detacheable base have an additional input
device under cros-ec, which reports SW_TABLET_MODE regarding
its base state (e.g. base flipped or detached).
