drm/connector: Add helper to get a connector type name
drm_connector.c contains a map of connector types (DRM_MODE_CONNECTOR_*)
to name strings, but doesn't expose it. This leads to drivers having to
store a similar map.
Add a new drm_get_connector_type_name() helper function that return a
name string for a connector type.
