drm/doc: Improve docs around connector (un)registration
Current code is quite a mess unfortunately, so also add a todo.rst entry to maybe fix it up eventually.

+connector register/unregister fixes
+-----------------------------------
+
+- For most connectors it's a no-op to call drm_connector_register/unregister
+ directly from driver code, drm_dev_register/unregister take care of this
+ already. We can remove all of them.
+
+- For dp drivers it's a bit more a mess, since we need the connector to be
+ registered when calling drm_dp_aux_register. Fix this by instead calling
+ drm_dp_aux_init, and moving the actual registering into a late_register
+ callback as recommended in the kerneldoc.
