PCI: Add pci_bus_clip_resource() to clip to fit upstream window
commit 0f7e7aee2f37119a32e6e8b63250922442528961 upstream.
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).
