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>;
