Subject: [PATCH v2] arm64: dts: mediatek: mt8195-cherry: Remove
 keyboard-backlight node

Commit 970c3a6b7aa3 ("mfd: cros_ec: Register keyboard backlight
subdevice") introduced support for detecting keyboard backlight
fuctionality through communication with the ChromeOS EC. This means that
the DT node is no longer used. Remove the unneeded node.
