I have no objection to SoC specific code moving out of arch-generic areas
into SoC specific areas - provided it doesn't cause any abonimations!

I suspect it was there because the iwmmxt stuff was also in that directory,
and at the time we didn't have the notifier in place to be able to properly
broadcast events that ISA extensions needed to react to context switching
etc.

Now that we do have all that in place, I don't think there's much reason
it lives in arch/arm/kernel.
