That's true but one of the goals with regmap is to be able to just use
the cache with the device powered off (lots of ASoC operation relies on
that for example) - regmap itself shouldn't ever be forcing the device
to be powered on.  One could equally say you shouldn't think about using
the hardware until you've got a regmap object with which to interact
with it, which is clearly the more urgent priority! :P
