UDL doesn't support vblank functionality so we don't need to initialize vblank here (we are able to send page flip completion events even without vblank initialization)
Moreover current drm_vblank_init call with num_crtcs > 0 causes sending DRM_EVENT_FLIP_COMPLETE event with zero timestamp every time. This breaks userspace apps (for example weston) which relies on timestamp value.
