This replaces the custom connector in the PL111 with the panel bridge helper. This works nicely for all standard panels, but since there are several PL11x-based systems that will need to use the dumb VGA connector bridge we use drm_of_find_panel_or_bridge() and make some headroom for dealing with bridges that are not panels as well, and drop a TODO in the code.
