Support for negative voltages is an implementation detail of Linux, IIRC
there's nothing in the generic regulator binding preventing it and even
if there were updates to the generic binding are what are relevant here
- they could start working with no updates to this binding.

These are covered by the generic regulator binding, no need to duplicate
the documentation here.
