I added a while line here and converted the last three remaining uses of
pci_dev in the initfn so that both fields could be renamed to parent_obj
as proof of complete conversion.

Thanks, queued this and the following one on qom-next:
https://github.com/afaerber/qemu-cpu/commits/qom-next

There was an overlap with Peter's usb/* PCIDevice patch, I believe this
one is a superset of the ohci part.
