All noise since we don't have CPU hotplug there.  However, they
did expose something very odd-looking in there - poke_viking()
does a bunch of identical btfixup each time it's called (i.e.
for each CPU).  That one is left alone for now; just the trivial
misannotation fixes.

Applied, thanks Al.

The local MMU register inits do need to happen for all cpus,
so what I'll do is move the btfixups to where we assign
poke_srmmu to poke_viking, so that they occur only once.
