iio: adc: ad7768-1: add support for ADAQ776x-1 ADC Family
Add support for ADAQ7767/68/69-1 series, which includes PGIA and
Anti-aliasing filter (AAF) gains. Unlike the AD7768-1, they do not
provide a VCM regulator interface.
The PGA gain is configured in run-time through the scale attribute,
if supported by the device. PGA is controlled by GPIOs provided in
the device tree.
The AAF gain is defined by hardware connections and should be specified
in the device tree.
