dt-bindings: i2c: xiic: Migrate i2c-xiic documentation to YAML

Xilinx IIC controller:

Required properties:

- compatible : Must be "xlnx,xps-iic-2.00.a"

- reg : IIC register location and length

- interrupts : IIC controller unterrupt

- #address-cells = <1>

- #size-cells = <0>

- clocks: Input clock specifier. Refer to common clock bindings.

Optional properties:

- Child nodes conforming to i2c bus binding

- clock-names: Input clock name, should be 'pclk'.

Example:

	axi_iic_0: i2c@40800000 {

		compatible = "xlnx,xps-iic-2.00.a";

		clocks = <&clkc 15>;

		interrupts = < 1 2 >;

		reg = < 0x40800000 0x10000 >;

		#size-cells = <0>;

		#address-cells = <1>;

	};
