Mediatek drm driver calls drm_dev_register() in .bind(). However, most panels sets orientation property relatively late, mostly in .get_modes() callback, since this is when they are able to get the connector and binds the orientation property to it, though the value should be known when the panel is probed. Let the drm driver check if the remote end point is a panel and if it contains the orientation property. If it does, set it before drm_dev_register() is called.
