drm: verisilicon: call atomic helper's plane state check even if no CRTC

Browse Source 
The `drm_atomic_helper_check_plane_state()` helper function needs to be
called even if the plane is bound to no CRTCs.

Remove the early return in the primary plane's atomic_check, and use
NULL for crtc_state in this situation.
