Move the bus_add_device() to a public API, so it can be applied to devices which are temporarily detached from their buses without being destroyed. This will be used after changes in PCI topology after hotplugging a bridge: buses may get their numbers changed, so their child devices must be reattached and their sysfs and proc files recreated.
