iio: adc: ad7191: add AD7191

AD7191 is a pin-programmable, ultralow noise 24-bit sigma-delta ADC designed for precision bridge sensor measurements. It features two differential analog input channels, selectable output rates, programmable gain, internal temperature sensor and simultaneous 50Hz/60Hz rejection.
