40bcc69b39 x86: k8 numa register active regions later
Impact: cleanup

don't register early, so we don't need to clear actived regions if it fail
to get node hash shift or wild set in nb config.

also remove nodeids array that is not needed

6ec6e0d9f2 srat, x86: add support for nodes spanning other nodes
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.
