dt-bindings: i2c: owl: Convert Actions Semi Owl binding to a schema 



Convert the Actions Semi Owl I2C DT binding to a YAML schema for
enabling DT validation.

Additionally, add a new compatible string corresponding to the I2C
controller found in the S500 variant of the Actions Semi Owl SoCs
family.

Actions Semiconductor Owl I2C controller



Required properties:



- compatible        : Should be one of the following:

		      - "actions,s700-i2c" for S700 SoC

		      - "actions,s900-i2c" for S900 SoC

- reg               : Offset and length of the register set for the device.

- #address-cells    : Should be 1.

- #size-cells       : Should be 0.

- interrupts        : A single interrupt specifier.

- clocks            : Phandle of the clock feeding the I2C controller.



Optional properties:



- clock-frequency   : Desired I2C bus clock frequency in Hz. As only Normal and

                      Fast modes are supported, possible values are 100000 and

                      400000.

Examples:



        i2c0: i2c@e0170000 {

                compatible = "actions,s900-i2c";

                reg = <0 0xe0170000 0 0x1000>;

                #address-cells = <1>;

                #size-cells = <0>;

                interrupts = <GIC_SPI 25 IRQ_TYPE_LEVEL_HIGH>;

                clocks = <&clock CLK_I2C0>;

                clock-frequency = <100000>;

        };
