    * Attach a pci bus device to a motherboard or pci-to-pci bridge bus.
    * Due to probe recursion it is possible for pci-to-pci bridges (such as
    * on the DELL2550) to attach before all the motherboard bridges have
    * attached.  We must call device_add_child() with the secondary id
    * rather then -1 in order to ensure that we do not accidently use
    * a motherboard PCI id, otherwise the device probe will believe that
    * the later motherboard bridge bus has already been probed and refuse
    * to probe it.  The result: disappearing busses!
