Ok, we can probably start from there. I think the right approach is to actually
kill pci_controller by merging it with the new host bridge structure.

Most of the resources are there now, we need to move the rest. We probably will
need a way to attach platform specific bits to it though, and a few hooks to
populate them but that isn't terribly hard.

Cheers,
Ben.
