regulator: Support regulators where voltage ranges are selectable
For example ROHM BD71837 and ROHM BD71847 Power management ICs have
regulators which provide multiple linear ranges. Ranges can be
selected by individual non contagious bit in vsel register. Add
regmap helper functions for selecting ranges.
