[PATCH 1/2] dt-bindings: iio: adc: Add the Ingenic X1600 ADC

[Olivier Louvignes]

The X1600's SAR ADC has four auxiliary channels and none of the
touchscreen or battery engines of the JZ47xx ADCs in
ingenic,adc.yaml, so it gets a binding of its own.

+description:
+  The SAR ADC of the Ingenic X1600 SoC, with four auxiliary input channels
