Previously we passed in a specifically named struct pci_controller to
determine if we had setup the particular PCI bus. Now we can search for
the struct so we dont have to depend on the name or the struct being
statically allocated.

Any comments or concerns on this? Some of my 8xxx PCI cleanup depends on the two patches.
