dt-bindings: serial: vt8500-uart: convert to json-schema 



Convert the VIA VT8500 and WonderMedia WM8xxx UART Controller to
newer DT schema. Created DT schema based on the .txt file which had
`compatible`, `reg`, `interrupts` and `clocks` as required properties.

Additions to the original binding
- changed the file name from vt8500-uart to via,vt8500-uart.yaml
- removed unnecessary alias from the example.

* VIA VT8500 and WonderMedia WM8xxx UART Controller



Required properties:

- compatible: should be "via,vt8500-uart" (for VIA/WonderMedia chips up to and

	including WM8850/WM8950), or "wm,wm8880-uart" (for WM8880 and later)



- reg: base physical address of the controller and length of memory mapped

	region.



- interrupts: hardware interrupt number



- clocks: shall be the input parent clock phandle for the clock. This should

	be the 24Mhz reference clock.



Aliases may be defined to ensure the correct ordering of the uarts.



Example:

	aliases {

		serial0 = &uart0;

	};



	uart0: serial@d8200000 {

		compatible = "via,vt8500-uart";

		reg = <0xd8200000 0x1040>;

		interrupts = <32>;

		clocks = <&clkuart0>;

	};
