For RK3399's GRF module, if we want to operate the graphic related grf
registers, we need to enable the pclk_vio_grf which supply power for VIO
GRF IOs, so it's better to introduce an optional grf clock in driver.

The hardware IC designed that VOP must output the RGB10 video format to
eDP contoller, and if eDP panel only support RGB8, then eDP contoller
should cut down the video data, not via VOP contoller, that's why we need
to hardcode the VOP output mode to RGA10 here.

Rockchip VOP couldn't output YUV video format for eDP controller, so
when driver detect connector support YUV video format, we need to hack
it down to RGB888.

Some boards don't need to declare a panel device node, like the
display interface is DP monitors, so it's necessary to make the
panel detect to an optional action.

eDP controller need to declare which vop provide the video source,
and it's defined in GRF registers.
But different chips have different GRF register address, so we need to
create a device data to declare the GRF messages for each chips.

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.
