Interesting, I dug up the old ux500 driver and even though
it doesn't have export/import hooked up, it does actually appear
to save/restore hardware state.  In fact it seems to do it multiple
times per request, even when it's unnecessary.

I'll try to see if the saving/restoring is subtly different
between ux500 and stm32.
