this should only run on exynos, as we're doing all our connector registration
in the core driver after all components are bound, so I guess something like
the following is needed:
if (dp->plat_data && dp->plat_data->dev_type == EXYNOS_DP)
drm_connector_register(connector);

this should be !gpio_is_valid ... i.e. only check the old property if the new
one is _not_ valid
