I get that the reference counting that the regulator API does is useful
here but this isn't a regulator so shouldn't be exposed as such,
particularly since this winds up being visible in the DT ABI.  I
could've sworn that someone did some helpers for this case but now I go
looking I can't find them, we certainly don't use any in the regulator
core.

Spurious unrelated change.
