dt-bindings:iio:impedance-analyzer:adi,ad5933 yaml conversion. 



The example in this one had a completely wrong compatible so I've
fixed that. Otherwise, a fairly simple conversion.

Note the driver itself is still in staging.  Looking back at the
last discussion around this, I think we were just waiting for some
test results on some refactors.  As such the binding should be stable
even if the driver might need a little more love and attention.

Required properties:

 - compatible : should be one of

		"adi,ad5933"

		"adi,ad5934"

 - reg : the I2C address.

 - vdd-supply : The regulator supply for DVDD, AVDD1 and AVDD2 when they

   are connected together.



Optional properties:

- clocks : external clock reference.

- clock-names : must be "mclk" if clocks is set.



Example for a I2C device node:



	impedance-analyzer@0d {

		compatible = "adi,adxl345";

		reg = <0x0d>;

		vdd-supply = <&vdd_supply>;

		clocks = <&ref_clk>;

		clock-names = "mclk";

	};
