One thing I've thought about
before is to create some kind of very simple "system controller"
framework based on regmap that lets you register a single global
"struct regmap" pointer from an SoC specific driver, and have drivers
call a function into that framework to get a reference to that
regmap.

This sounds like a good idea. "misc-bit-poking" is something a lot
of systems are doing.

I haven't fully grasped regmap so that I can say whether that is the
proper abstraction or not though. But I trust you on this...
