Benjamin Herrenschmidt 2fae0a524b powerpc: Add memory clobber to mtspr()
Without this clobber, mtspr can be re-ordered by gcc vs. surrounding
memory accesses. While this might be ok for some cases, it's not in
others and I'm not confident that all callers get it right (In fact
I'm sure some of them don't).

So for now, let's make mtspr() itself contain a memory clobber until
we can audit and fix everything, at which point we can remove it
if we think it's worth doing so.
