platform/chrome: cros_kbd_led_backlight: Remove OF match

Browse source 
After applying 4c03a44e26 ("arm64: dts: mediatek: mt8195-cherry: Remove
keyboard-backlight node"), there are no users for using the OF match.
Instead, the device is added via drivers/mfd/cros_ec_dev.c by
970c3a6b7a ("mfd: cros_ec: Register keyboard backlight subdevice").

Remove the OF match.
