mb/clevo/l140cu: add panel settings to the dt and hook up GMA ACPI

Add the panel settings dumped from vendor firmware and hook up
drivers/intel/gma, which will be required for brightness control.

Keyboard brightness control still requires ACPI code. This will be done
in a separate change later.

Test: Panel gets enabled when the payload starts on Clevo L141CU.
