x86/PCI: amd: factor out MMCONFIG discovery

commit 24d25dbfa63c376323096660bfa9ad45a08870ce upstream.

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.
