commit 1a70ca89d59c7c8af006d29b965a95ede0abb0da upstream.
Returns EPROBE_DEFER when of_drm_find_bridge() fails, this is consistent with what all the other DRM bridge drivers are doing and this is required since the bridge might not be there when the driver is probed and this should not be a fatal failure.
