As part of the transitition of the DP encoder to a DRM bridge, turn the DRM encoder into a dummy encoder and move it out of the DP code, to the DPSUB core. DP encoder operations are handled by the DP bridge, which is now attached to the encoder. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
