drm/sysfs: rename drm_sysfs_connector_status_event()

Browse Source 
Rename drm_sysfs_connector_status_event() to
drm_sysfs_connector_property_event(). Indeed, "status" is a bit
vague: it can easily be confused with the connected/disconnected
status of the connector. This function has nothing to do with
connected/disconnected: it merely sends a notification that a
connector's property has changed (e.g. HDCP, privacy screen, etc).
