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` and `interrupts` as the required properties.
This binding is used by Actions S500 and S700 SoC.

Changes in v2
- Added Clock property to fix the warning of `dts/actions/s700-cubieboard7.dtb:
serial@e0126000: Unevaluated properties are not allowed
('clocks' was unexpected)` thrown by `make dtbs_check`
- Changed the compatible identifier for having both the compatible names
earlier was throwing `owl-s500-cubieboard6.dtb: serial@b0120000: compatible:
['actions,s500-uart', 'actions,owl-uart'] is too long` warning.
- Updated commit message

-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.
