As long as we can get hold of the regmap that would be fine. I pressume the
idea is to have the kpss-gcc using syscon, just like the rpm. But hopefully the
syscon patches that are floating around (merged?) will allow any driver to
expose a "syscon regmap".

I haven't seen any indications of us using more than this bit. If we want to do
that, we could simply make it <&apcs 8 2 &apcs 8 3 &apcs 8 4> (or whatever
those indices are). That way this should be easy it keep compatible.
