FROMLIST: drm/rockchip: get rid of rockchip_drm_crtc_mode_config

We need to take care of the vop status when use
rockchip_drm_crtc_mode_config, if vop is disabled,
the function would failed, that is terrible.

Save output_type and output_mode into rockchip_crtc_state,
it's nice to make them into atomic.
