soc/amd/phoenix: add get_pci_routing_table stub for non-FSP case
In the FSP case we get this info via a HOB. It's currently unclear if
we'll get a data structure for this from openSIL or if we'll end up
being able to just read the configuration fro the hardware, so add a
get_pci_routing_table stub for now to be able to build.
