I have a regulator that's being configured from DT as:
regulator-min-microvolt = <2950000>;
regulator-max-microvolt = <2950000>;

In the consumer I do regulator_set_voltage(2.95V).

As min == max the voltage is applied by the regulator framework on registration
of the regulator; and the regulator_set_voltage() fails as
REGULATOR_CHANGE_VOLTAGE is not set for this regulator.

So we should be changing the code to allow a set_voltage() that sets the
voltage to the existing voltage regardless of constraints allowing a
change then - that's what the underlying issue is.  Your change wouldn't
cover the case where the hardware defualt is being used for example.
