The OF platform code sets up simple bus only devices (i.e. devices that won't match with any other driver) to get probed by the simple-pm-bus to keep fw_devlink from blocking probe() or sync_state() [1] callbacks of other devices. There's no need to populate the child devices since the OF platform code would do that anyway, so return early for these simple bus only devices.
