[PATCH RFC] regulator: mc13xxx: Populate selector frommc13xxx_fixed_regulator_set_voltage

[Axel Lin]

This was missing until now and the underlying
_regulator_do_set_voltage is using this value when calling list_voltage.

Not very sure if we should implement set_voltage callback for fixed voltage.
( Other drivers do not implement set_voltage callback for fixed voltage.
Since the voltage is fixed, implement set_voltage callback seems does not make sense.)

If we do implement the callback, we need to populate selector.
Or alternative, we can just remove mc13xxx_fixed_regulator_set_voltage.
