[PATCH v3] dt-bindings: serial: vt8500-uart: convert to json-schema

[Kanak Shilledar]

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.

Changes in v3:
- Removed Rob and myself from maintainers and added Alexey.
- Fixed commit message which mentioned "greg and jiri as maintainers".
- Elaborated changelog for v2.
Changes in v2:
- Rebased changes
- Changed maintainers to have Rob and remove Greg and Jiri. VT8500 is
orphaned according to the maintainers file.
- Replaced `compatible` property description with comments.

-* 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>;
