So, clearly that's going to be the behaviour at the system level but the
consumers aren't going to know that.  If the consumer supports some of
the supplies being enabled and disabled separately then it will rely on
the regulator core reference counting to keep the supply enabled if
there are other reasons to do so.  This is how things would work if both
supplies came from the same regulator so I'd expect us to preserve the
same behaviour.
