Makes no real difference, but if you know the MIPS tree never ends up
with pdev->bus = NULL for the root bus then its a trivial change

Two reasons
1. It makes the entire system more consistent
2. It means we can remove the (usually) unsafe pci_find_slot API
(and #3 sort of... it means the pci fake hotplug testing works with this
device too)
