Replace the manual connector implementation based on drm_panel with the drm_panel_bridge helper. This simplifies the mxsfb driver by removing connector-related code, and standardizing all pipeline control operations on bridges. A hack is needed to get hold of the connector, as that's our only source of bus flags and formats for now. As soon as the bridge API provides us with that information this can be fixed.
