This makes 4xx embedded platforms re-assign all PCI resources as we pretty much never care about what the various firmwares have done on these, it's generally not compatible with the way the kernel will map the bridges. We still need to also enable bus renumbering on some of them, but I will do that from a separate patch after I've fixed 4xx PCIe to handle all bus numbers.
