This looks good except for this bit where we read the regulator name out
of the DT, that's generally a sign of bad practice for things that are
less simple passives than things like this or fixed voltage regulators.
As with the supplies for fixed voltage regulators just pick a name for
the supply (ctrl seems fine to me) and use that, neither option is
perfect but at elast this less typing for everyone and it's consistent
with what other similar things are already doing.
