Use drm_connector's helpers enable_hpd and disable_hpd to enable and
disable HPD automatically by the means of drm_kms_helper_poll_*
functions. As the drm_bridge_connector_enable_hpd() and
drm_bridge_connector_disable_hpd() functions are now unused, replace
them with stubs to ease driver migration.
