x86, amd-nb: Cleanup AMD northbridge caching code
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.
