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

  adi,aaf-gain-bp:

    description: |

       Specifies the gain applied by the Analog Anti-Aliasing Filter (AAF)

       to the ADC input in basis points (one hundredth of a percent).

       The hardware gain is determined by which input pin(s) the signal goes

       through into the AAF. The possible connections are:

       * For the ADAQ7767-1: Input connected to IN1±, IN2± or IN3±.

       * For the ADAQ7769-1: OUT_PGA pin connected to IN1_AAF+, IN2_AAF+,

         or IN3_AAF+.
