dt-bindings: i2c: renesas,iic-emev2: Convert to json-schema 



Convert the Renesas EMMA Mobile EV2 IIC Interface (IIC) Device Tree
binding documentation to json-schema.

Document missing properties.
Update the example to match reality.

Device tree configuration for Renesas EMEV2 IIC controller



Required properties:

- compatible      : "renesas,iic-emev2"

- reg             : address start and address range size of device

- interrupts      : specifier for the IIC controller interrupt

- clocks          : phandle to the IP core SCLK

- clock-names     : must be "sclk"

- #address-cells  : should be <1>

- #size-cells     : should be <0>



Example:



	iic0: i2c@e0070000 {

		#address-cells = <1>;

		#size-cells = <0>;

		compatible = "renesas,iic-emev2";

		reg = <0xe0070000 0x28>;

		interrupts = <0 32 IRQ_TYPE_EDGE_RISING>;

		clocks = <&iic0_sclk>;

		clock-names = "sclk";

	};
