[POWERPC] Add thread_info_cache_init() weak hook
Some architectures need to maintain a kmem cache for thread info structures. The next commit adds that to powerpc to fix an alignment problem. There is no good arch callback to use to initialize that cache that I can find, so this adds a new one in the form of a weak function whose default is empty.
