dt-bindings: serio: Convert Allwinner PS2 controller to a schema 



The older Allwinner SoCs have a PS2 controller that is supported in Linux,
with a matching Device Tree binding.

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

* Device tree bindings for Allwinner A10, A20 PS2 host controller



A20 PS2 is dual role controller (PS2 host and PS2 device). These bindings are

for PS2 A10/A20 host controller. IBM compliant IBM PS2 and AT-compatible keyboard

and mouse can be connected.



Required properties:



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

 - compatible      : Should be as of the following:

                     - "allwinner,sun4i-a10-ps2"

 - interrupts      : The interrupt line connected to the PS2.

 - clocks          : The gate clk connected to the PS2.





Example:

	ps20: ps2@01c2a000 {

		compatible = "allwinner,sun4i-a10-ps2";

		reg = <0x01c2a000 0x400>;

		interrupts = <0 62 4>;

		clocks = <&apb1_gates 6>;

	};
