MN10300: SMP: Differentiate local cache flushing
Differentiate local cache flushing from global cache flushing so that they can
be done differently on SMP systems.
Rename the cache functions from:
mn10300_[id]cache_*()
to:
mn10300_[id]_localcache_*()
and on a UP system, assign the global labels to the local labels.
