dt-bindings: pwm: Convert Allwinner PWM to a schema
The Allwinner SoCs have a PWM controller 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. Signed-off-by: Maxime Ripard <maxime.ripard@bootlin.com>

-Allwinner sun4i and sun7i SoC PWM controller
-
-Required properties:
- - compatible: should be one of:
- - "allwinner,sun4i-a10-pwm"
- - "allwinner,sun5i-a10s-pwm"
- - "allwinner,sun5i-a13-pwm"
- - "allwinner,sun7i-a20-pwm"
- - "allwinner,sun8i-h3-pwm"
- - "allwinner,sun50i-a64-pwm", "allwinner,sun5i-a13-pwm"
- - "allwinner,sun50i-h5-pwm", "allwinner,sun5i-a13-pwm"
- - reg: physical base address and length of the controller's registers
- - #pwm-cells: should be 3. See pwm.txt in this directory for a description of
- the cells format.
- - clocks: From common clock binding, handle to the parent clock.
-
-Example:
-
- pwm: pwm@1c20e00 {
- compatible = "allwinner,sun7i-a20-pwm";
- reg = <0x01c20e00 0xc>;
- clocks = <&osc24M>;
- #pwm-cells = <3>;
- };
