powerpc/cacheinfo: add cacheinfo_teardown, cacheinfo_rebuild
[ Upstream commit d4aa219a074a5abaf95a756b9f0d190b5c03a945 ]
Allow external callers to force the cacheinfo code to release all its
references to cache nodes, e.g. before processing device tree updates
post-migration, and to rebuild the hierarchy afterward.
CPU online/offline must be blocked by callers; enforce this.
