Adaptions to the changes of the AMD northbridge caching code: instead
of a bool in each l3 struct, use a flag in amd_northbridges.flags to
indicate L3 cache index disable support; use a pointer to the whole
northbridge instead of the misc device in the l3 struct; simplify the
initialisation; dynamically generate sysfs attribute array.

Support more than just the "Misc Control" part of the northbridges.
Support more flags by turning "gart_supported" into a single bit flag
that is stored in a flags member. Clean up related code by using a set
of functions (amd_nb_num(), amd_nb_has_feature() and node_to_amd_nb())
instead of accessing the NB data structures directly. Reorder the
initialization code and put the GART flush words caching in a separate
function.

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.

AMD CPU family 0x15 still supports GART for compatibility reasons.

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.
