I explained in my mail why I think that the current implementation of
the dummy regulator is not suitable for things apart from debugging.

My main concern with the fixed regulator is that it needs quite much
boilerplate code just to say that we have no regulator at all for a
given device. That could also be handled with a helper function which
registers a fixed regulator and only takes the regulator_consumer_supply
as an argument. Would that be ok for you?
