For example, If the physical address layout on a two node system with 8 GB
memory is something like:
node 0: 0-2GB, 4-6GB
node 1: 2-4GB, 6-8GB
Current kernels fail to boot/detect this NUMA topology.
ACPI SRAT tables can expose such a topology which needs to be supported.

This just adds the PCI IDs of AMD's family 10h and 11h CPU's northbridges to
k8topology discovery.

We shoud use core id bits instead of max cores, in case later with AMD
downcores Quad core Opteron.
