drm: Remove dp mst register connector callbacks

drm_dp_mst_port_add_connector() directly calls the
drm_connector_register() now and
drm_dp_mst_topology_mgr_cbs.register_connector callback is not getting
called anymore.

Hence remove all drm_dp_mst_topology_mgr_cbs.register_connector
callbacks.

This is the preparatory step for removing the
drm_dp_mst_topology_mgr_cbs.register_connector callback hook.

The removal is done with below sementic patch:

@r1@
identifier func, E;
@@
struct drm_dp_mst_topology_cbs E = {
	...,
-        .register_connector = func
};

@delete depends on r1@
identifier r1.func;
