regulator: core: Factor out regulator_map_voltage
_regulator_call_set_voltage has code to translate a minimum/maximum voltage pair into a selector. This code is useful for others aswell, so create a regulator_map_voltage function. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Mark Brown <broonie@kernel.org>
