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. Signed-off-by: Mark Yao <mark.yao@rock-chips.com> Tested-by: John Keeping <john@metanate.com>
