From: Kanak Shilledar <kanakshilledar111@xxxxxxxxxxxxxx>
Convert the Actions Semi Owl UART to newer DT schema.
Created DT schema based on the .txt file which had
`compatible`, `reg`, `clocks` 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.
Implemented a full node example for the UART, referenced S500 SoC
devicetree include.

Changes in v3
- Updated commit message to make it more verbose
- Extended the DTS example by adding clocks. Referred the S500.dtsi
for adding clocks property.
- Added Reviewed-by tag

-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.
