If we get rid of the struct pci_bus * dependency, then we can easily
add the _PRT before doing PCI enumeration behind the bridge, and we
can remove the _PRT after removing the PCI devices.  I think this is
one small step toward getting rid of the add/start and stop/remove
split.

I'm going to work on doing this if nobody else is interested.

I'm not sure if that is needed.

After patches that is using pci_host_bridge_bus_type and pci_bus_type
notification, we can remove
acpi_pci_root_start.

please check patches in my for-pci-next branch: it include jiang's 7
patches about notifier, and my kill pci_root_buses and etc.
