regulator: da9055: Fix return wrong selector in da9055_regulator_get_voltage_sel

We do "selector += info->volt.v_offset" in da9055_regulator_set_voltage_bits() to take care of voltage range that does not start with 0 offset. Thus in da9055_regulator_get_voltage_sel() we should do corresponding "sel -= volt.v_offset" before returning selector.
Otherwise, we pass wrong selector for list_voltage callback.

No, we should just be using raw register values as the selectors and fixing this in list_voltage() by returning 0 for invalid selectors.
