dt-bindings: iio: adc: Add common ADCs properties to a separate file



There are several ADC drivers that depend on the same device tree
bindings. Rather than continue to duplicate the properties, this patch
adds a common adc binding document that can be referenced. For beginning,
only two properties are documented.

		Common ADCs properties

		Optional properties for child nodes:
		- bipolar : Boolean, if set the channel is used in bipolar mode.
		- diff-channels : Differential channels muxed for this ADC. The first value
		specifies the positive input pin, the second value the negative
		input pin.

		Example:
		adc@0 {
		compatible = "some,adc";
		...
		channel@0 {
		bipolar;
		diff-channels = <0 1>;
		...
		};

		channel@1 {
		diff-channels = <2 3>;
		...
		};
		};
