[v9,0/4] Separate panel orientation property creating and value setting

Message

Some drivers, eg. mtk_drm and msm_drm, rely on the panel to set the
orientation. Panel calls drm_connector_set_panel_orientation() to create
orientation property and sets the value. However, connector properties
can't be created after drm_dev_register() is called. The goal is to
separate the orientation property creation, so drm drivers can create it
earlier before drm_dev_register().

After this series, drm_connector_set_panel_orientation() works like
before, so it won't affect other drm drivers. The only difference is that
some drm drivers can call drm_connector_init_panel_orientation_property()
earlier.
