Many regulator drivers implement voltage setting by looping through a table of possible values, normally because the set of available voltages can't be mapped onto selectors with simple calcuation. Factor out these loops by providing a variant of set_voltage() which takes a selector rather than a voltage range as an argument and implementing a loop through the available selectors in the core. This is not going to be suitable for use with all devices as when the regulator voltage can be mapped onto selector values with a simple calculation the linear scan through the available values will be more expensive than just doing the calculation, especially for regulators that provide fine grained voltage control.
