Most systems' PCIe outbound map windows have non-zero physical addresses,
but the possibility of encountering zero increased with commit
700cafbb642b ("PCI: dwc: ep: Add bus_addr_base for outbound window").

I don't know what commit 700cafbb642b is.  It doesn't appear
upstream, and there's no subject line or patch match for
bus_addr_base.
