Subject: [PATCH] arm64: dts: mt8183: juniper: Remove CrosEC base detection node

The cbas node is used to describe base detection functionality in the
ChromeOS EC, which is used for units that have a detachable keyboard and
thus rely on this functionality to switch between tablet and laptop
mode.

The juniper-sku16 machine is a convertible, meaning the keyboard can be
flipped but not detached. The detection for the keyboard getting
flipped is handled by the driver bound to the keyboard-controller
node in the EC.

Since there is no base detection in this machine, and the device backed
by this node fails to probe and goes unused, delete the node from the
DT.
