dt-bindings: i2c: meson: convert to yaml 



Now that we have the DT validation in place, let's convert the device tree
bindings for the Amlogic I2C Controller over to YAML schemas.

Amlogic Meson I2C controller



Required properties:

 - compatible: must be:

	"amlogic,meson6-i2c" for Meson8 and compatible SoCs

	"amlogic,meson-gxbb-i2c" for GXBB and compatible SoCs

	"amlogic,meson-axg-i2c"for AXG and compatible SoCs



 - reg: physical address and length of the device registers

 - interrupts: a single interrupt specifier

 - clocks: clock for the device

 - #address-cells: should be <1>

 - #size-cells: should be <0>



For details regarding the following core I2C bindings see also i2c.txt.



Optional properties:

- clock-frequency: the desired I2C bus clock frequency in Hz; in

  absence of this property the default value is used (100 kHz).



Examples:



	i2c@c8100500 {

		compatible = "amlogic,meson6-i2c";

		reg = <0xc8100500 0x20>;

		interrupts = <0 92 1>;

		clocks = <&clk81>;

		#address-cells = <1>;

		#size-cells = <0>;

	};
