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.

Changes in v3:
- foget remove rockchip_drm_crtc_mode_config function in v2, remove it in v3.
Changes in v2:
Advised by John Keeping
- use atomic crtc state to transmit output_type and output_mode
