It's not really useful for the regulator subsystem to directly bind to
the device as something needs to actually control it, the idea is that
this binding is included by reference in the bindings for specific
devices.

On the other hand the case is pretty important for SI units

The name will be fixed by the individual device bindings, this is
specifying the general form of a supply property.  Each device binding
will define the set of supplies that the device can use.
