dt-bindings: clocks: Convert Allwinner A80 USB clocks to a schema
The Allwinner A80 SoC has a USB clocks controller that is supported in Linux, with a matching Device Tree binding. Now that we have the DT validation in place, let's convert the device tree bindings for that controller over to a YAML schemas.

-Allwinner A80 USB Clock Control Binding
----------------------------------------
-
-Required properties :
-- compatible: must contain one of the following compatibles:
- - "allwinner,sun9i-a80-usb-clocks"
-
-- reg: Must contain the registers base address and length
-- clocks: phandle to the clocks feeding the USB subsystem. Two are needed:
- - "bus": the bus clock for the whole USB subsystem
- - "hosc": the high frequency oscillator (usually at 24MHz)
-- clock-names: Must contain the clock names described just above
-- #clock-cells : must contain 1
-- #reset-cells : must contain 1
-
-Example:
-usb_clocks: clock@a08000 {
- compatible = "allwinner,sun9i-a80-usb-clks";
- reg = <0x00a08000 0x8>;
- clocks = <&ccu CLK_BUS_USB>, <&osc24M>;
- clock-names = "bus", "hosc";
- #clock-cells = <1>;
- #reset-cells = <1>;
-};
