drm/omap: Add support for drm_panel
Hook up drm_panel support in the omapdrm driver. The change is
relatively simply as the way has been paved by drm_bridge support
already. In addition to looking up, attaching to and detaching from the
panel, we only need to add panel support in the connector .get_modes()
handler, take connector bus flags (set by the panel) into account, and
enable/disable the panel in the encoder enable/disable operations
handlers.
