We need to implement the get_dev_path method for the css bus, or else we might end up with two different devices having the same qdev_path. This was noticed when adding two scsi_hd controllers: The SCSIBus code will produce a non-unique dev_path for vmstate usage if the parent bus does not provide the get_dev_path method. We simply use the device's bus id, as this is unique and we won't have any deeper hierarchy from a channel subsystem perspective anyway. Note that we need to disable this for older machine versions, as this changes the migration format.
