drm/display: hdmi-state-helper: Sync SCDC state on hotplug
drm_atomic_helper_connector_hdmi_hotplug() does not currently
synchronize SCDC status on hotplug events, leaving the scrambler state
potentially inconsistent after (re)connect.
Hook drm_connector_hdmi_sync_scdc() into both the connect and disconnect
paths, replacing the existing TODOs around missing scrambler handling.
Note that per .detect_ctx() contract, implementations shall return a
drm_connector_status value or -EDEADLK, nothing else. Therefore, handle
deadlocks and just report any other errors. For consistency, also
report the errors from drm_edid_connector_update().
