Thanks for your work on this, from a sunxi pov it looks good
(once Marc's remarks are fixed).

Also many thanks to Marc for the thorough review. I've been treating the
PSCI stuff as a black-box, only doing mostly style / sanity reviews, so
the thorough review is appreciated a lot.

Lets do a v2 and try to land this soon-ish ?
