x86/PCI: amd: factor out MMCONFIG discovery
This factors out the AMD native MMCONFIG discovery so we can use it outside amd_bus.c. amd_bus.c reads AMD MSRs so it can remove the MMCONFIG area from the PCI resources. We may also need the MMCONFIG information to work around BIOS defects in the ACPI MCFG table.
