Why?  If the data is already saved for you, then there's no reason not
to use it.  The fact that some generic code doesn't give you _exactly_
everything you'd want is not a reason to avoid it.

The cleanup for imx6q is that it would no longer have to have its own
distinct code for saving the register values - and that's a danmed good
thing.

The idea here is that we consolidate what _can_ be consolidated (which
is the register saving.)

If you feel soo strongly that it's not worth doing, then let's stop
wasting time and review effort on this, and instead have _every_ SoC
implementing their own private L2 cache handling on resume.
