dt-bindings: iio: adc: ad7768-1: add new supported parts

Add compatibles for supported parts in the ad7768-1 family:
ADAQ7767-1, ADAQ7768-1 and ADAQ7769-1

Add property and checks for AFF gain, supported by ADAQ7767-1
and ADAQ7769-1, and for PGA gain, supported by ADAQ7768-1
and ADAQ7769-1:
adi,aaf-gain-bp
pga-gpios
