PCI: Add pci_upstream_bridge()
This adds a pci_upstream_bridge() interface to find the PCI-to-PCI bridge
upstream from a device. This is typically just "dev->bus->self", but in
the case of a VF on a virtual bus, we have to start from the corresponding
PF. Returns NULL if there is no upstream PCI bridge, i.e., if the device
is on a root bus.
