drm/armada: redo locking and atomics for armada_drm_crtc_complete_frame_work() We can do better with armada_drm_crtc_complete_frame_work() - we can avoid taking the event lock unless a call to drm_send_vblank_event() is required, and using cmpxchg() and xchg(), we can eliminate the locking around dcrtc->frame_work entirely.
