Other entities (drm_connector.crtc, drm_encoder.crtc, etc.) have
pointer to other currently bound entities. They are all considered
relevant only for non-atomic drivers, and generally perceived as
deprecated in favour of the equivalent pointers in the atomic states.

It used to be useful because we didn't have alternatives, but now that
we do, let's make sure it's done for drm_bridge.encoder too.
