[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.
