Subject: x86, k8-gart: Decouple handling of garts and northbridges
So far we only provide num_k8_northbridges. This is required in
different areas (e.g. L3 cache index disable, GART). But not all AMD
CPUs provide a GART. Thus it is useful to split off the GART handling
from the generic caching of AMD northbridge misc devices.

Subject: x86, k8: Rename k8.[ch] to amd_nb.[ch] and CONFIG_K8_NB to
CONFIG_AMD_NB
The file names are somehow misleading as the code is not specific to
AMD K8 CPUs anymore. The files accomodate code for other AMD CPU
northbridges as well.
Same is true for the config option which is valid for AMD CPU
northbridges in general and not specific to K8.
