Driver core: add bus_sort_breadthfirst() function

The PCI core wants to reorder the devices in the bus list.  So move this
functionality out of the pci core and into the driver core so that
anyone else can also do this if needed.  This also lets us change how
struct device is attached to drivers in the future without messing with
the PCI core.
