This fits better with the drm_bridge callbacks for when this driver becomes a drm_bridge.

Please group the tda998x_encoder_* functions together, and in order of their use in the function vtables, and just above the function vtables. That'll mean that all the encoder veneers are together, all the bridge veneers are together, etc, and probably means later on it's easier to remove the encoder stuff (as all the encoder code will be in one hunk rather than scattered throughout the file.)
Thanks.
