OFF is currently not a regulator operating mode but is a regulator
operating state (e.g. state is either ON or OFF). The modes define the
ON (supplying power) operating modes supported by a regulator. I should
probably add some more docs/comments here......

I assume the TWL4030's ACTIVE and STANDBY modes supply power and
probably all share the same register/bits with OFF (thus making it more
tightly coupled in the hardware).

The other two patches are fine. Would you be able to resend the first
without the OFF mode patch changes.
