When connector is created, if connector->polled is DRM_CONNECTOR_POLL_CONNECT then drm_kms_helper_hotplug_event function isn't called at drm_helper_hpd_irq_event because the function will be called only in case of DRM_CONNECTOR_POLL_HPD.
So this patch sets always DRM_CONNECTOR_POLL_HPD flag to connector->polled of parallel panel driver at connector creation.
