Obviously having hardcoded values for the drm_plane .possible_crtcs field is not going to work. For primary and cursor planes, the value is set by drm_crtc_init_with_planes. We just need to set it for overlay planes. We also fix the value set for the RGB encoder, by referencing the crtc set in sun4i_drv.
