drm/rockchip: update rockchip_drm_platform_shutdown

Browse Source 
The reason to implement shutdown is for the fake shutdown on the box
product. but after implement this function, panel will still display
overlay plane for about two second when power off. so we directly
close crtc instead of rockchip_drm_sys_suspend() when shutdown.
