drm/panel: himax-hx83102: Add support for DSI DCS backlight control

Browse source

The HTF065H045 panel based on the HX83102 controller does use DCS
commands for controlling backlight brightness. Make the driver fall back
to DCS when no external backlight has been defined in the device tree,
like many other drivers do.
