Add device tree binding documentation for the Analog Devices AD5446 family of Digital-to-Analog Converters and derivative devices from Texas Instruments. There's both SPI and I2C interfaces and feature resolutions ranging from 8-bit to 16-bit. The binding covers 29 derivatives devices including the AD5446 series, AD5600 series, AD5620/5640/5660 variants with different voltage ranges, and TI DAC081s101/DAC101s101/DAC121s101 devices.
