ASoC: dt-bindings: adi,adau17x1: Convert to DT schema

Convert the binding document for adi,adau17x1 from txt to yaml
so one could validate dt-entries correctly and any future additions
can go into yaml format. Add address and size cells to example to
prevent errors regarding reg format.

-Analog Devices ADAU1361/ADAU1461/ADAU1761/ADAU1961/ADAU1381/ADAU1781
-
-Required properties:
-
- - compatible:		Should contain one of the following:
-			"adi,adau1361"
-			"adi,adau1461"
-			"adi,adau1761"
-			"adi,adau1961"
-			"adi,adau1381"
-			"adi,adau1781"
-
- - reg:			The i2c address. Value depends on the state of ADDR0
-			and ADDR1, as wired in hardware.
-
-Optional properties:
- - clock-names:		If provided must be "mclk".
- - clocks:		phandle + clock-specifiers for the clock that provides
-			the audio master clock for the device.
-
-Examples:
-#include <dt-bindings/sound/adau17x1.h>
-
-	i2c_bus {
-		adau1361@38 {
-			compatible = "adi,adau1761";
-			reg = <0x38>;
-
-			clock-names = "mclk";
-			clocks = <&audio_clock>;
-		};
-	};
