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

k8_scan_nodes is global and needs a prototype. Add the header file
which contains it.

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.

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