I think we could also move the declaration from include/linux/pci.h to
drivers/pci/pci.h, right?

I guess there's some argument for keeping it in include/linux/pci.h
next to the pci_walk_bus() declaration, but I certainly don't want to
encourage more use of either one, especially outside the PCI core.
