x86, cacheinfo: Remove NUMA dependency, fix for AMD Fam10h rev D1

commit f619b3d8427eb57f0134dab75b0d217325c72411 upstream.

The show/store_cache_disable routines depend unnecessarily on NUMA's
cpu_to_node and the disabling of cache indices broke when !CONFIG_NUMA.
Remove that dependency by using a helper which is always correct.

While at it, enable L3 Cache Index disable on rev D1 Istanbuls which
sport the feature too.
