[U-Boot] pci_hose_{bus_to_phys,phys_to_bus} and inbound memory

We have an issue with inbound windows overlapping outbound windows. This is fine, but it does mean that pci_hose_{bus_to_phys,phys_to_bus} can return the wrong thing.

I was wondering if there was any issue if PCI_REGION_MEMORY was set for a region if we skipped that region in the lookup functions:

pci_hose_phys_to_bus(...) { ... for (i = 0; i < hose->region_count; i++) { res = &hose->regions[i];

if (((res->flags ^ flags) & PCI_REGION_TYPE) != 0) continue;

if (reg->flags & PCI_REGION_MEMORY) continue; ...

any issues with this change? If not I'll work up a proper patch.
