dt-bindings: serial: actions,owl-uart: convert to dtschema 



Convert the Actions Semi Owl UART to newer DT schema.
Created DT schema based on the .txt file which had
`compatible`, `reg` and `interrupts` as the
required properties. This binding is used by Actions S500, S700
and S900 SoC. S700 and S900 use the same UART compatible string.

Actions Semi Owl UART



Required properties:

- compatible :  "actions,s500-uart", "actions,owl-uart" for S500

                "actions,s900-uart", "actions,owl-uart" for S900

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

- interrupts :  Should contain UART interrupt.





Example:



		uart3: serial@b0126000 {

			compatible = "actions,s500-uart", "actions,owl-uart";

			reg = <0xb0126000 0x1000>;

			interrupts = <GIC_SPI 32 IRQ_TYPE_LEVEL_HIGH>;

		};
