The DP needs to have resumed once the DRM driver calls
drm_atomic_helper_resume, otherwise the DP clock is still disabled when
the DRM core enables the DP bridge.
Would be nice to use device_pm_wait_for_dev to synchronize these
devices, but the DRM device doesn't know what specific implementation
this bridge has.

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.

Rockchip have three clocks for dp controller, we leave pclk_edp
to analogix_dp driver control, and keep the sclk_edp_24m and
sclk_edp in platform driver.
