[PATCH RESEND v4] dt-bindings: pwm: Convert Amlogic Meson PWM binding

[Heiner Kallweit <hkallweit1@gmail.com>]

Convert Amlogic Meson PWM binding to yaml.

Reviewed-by: Rob Herring <robh@kernel.org>

Seems patch got lost over the question who takes it.
Please apply through the pwm tree.

v2:
- fix clocks and clock-names
- consider that more than one compatible may be set
v3:
- remove minItem/maxItem properties for compatible
v4:
- remove not needed "items" before "enum"

-Amlogic Meson PWM Controller
-============================
-
-Required properties:
-- compatible: Shall contain "amlogic,meson8b-pwm"
-                         or "amlogic,meson-gxbb-pwm"
-                         or "amlogic,meson-gxbb-ao-pwm"
-                         or "amlogic,meson-axg-ee-pwm"
-                         or "amlogic,meson-axg-ao-pwm"
-                         or "amlogic,meson-g12a-ee-pwm"
-                         or "amlogic,meson-g12a-ao-pwm-ab"
-                         or "amlogic,meson-g12a-ao-pwm-cd"
-- #pwm-cells: Should be 3. See pwm.yaml in this directory for a description of
-  the cells format.
-
-Optional properties:
-- clocks: Could contain one or two parents clocks phandle for each of the two
-  PWM channels.
-- clock-names: Could contain at least the "clkin0" and/or "clkin1" names.
-
-Example:
-
-	pwm_ab: pwm@8550 {
-		compatible = "amlogic,meson-gxbb-pwm";
-		reg = <0x0 0x08550 0x0 0x10>;
-		#pwm-cells = <3>;
-		clocks = <&xtal>, <&xtal>;
-		clock-names = "clkin0", "clkin1";
