drm/panel: Add an API to allow drm to set orientation from panel
Panels usually call drm_connector_set_panel_orientation(), which is
later than drm/kms driver calling drm_dev_register(). This leads to a
WARN().
The orientation property is known earlier. For example, some panels
parse the property through device tree during probe.
Add an API to return the property from panel to drm/kms driver, so the
drivers are able to call drm_connector_set_orientation_from_panel() before
drm_dev_register().
