PCI: Add pci_bus_clip_resource() to clip to fit upstream window
Add pci_bus_clip_resource(). If a PCI-PCI bridge window overlaps an
upstream bridge window but is not completely contained by it, this clips
the downstream window so it fits inside the upstream one.
No functional change (this adds the function but no callers).
