iio: add ad5761 DAC driver

ad5761 is a 1-channel DAC with configurable output range. The driver uses the regulator interface for its voltage ref. It shares its register layout with ad5761r, ad5721 and ad5721r. Differences: ad5761* are 16 bit, ad5721* are 12 bits. ad57*1r have an internal reference.
