x86, amd-nb: Complete the rename of AMD NB and related code
Not only the naming of the files was confusing, it was even more so for
the function and variable names.
Renamed the K8 NB and NUMA stuff that is also used on other AMD
platforms. This also renames the CONFIG_K8_NUMA option to
CONFIG_AMD_NUMA and the related file k8topology_64.c to
amdtopology_64.c. No functional changes intended.
