Convert the binding doc to dt schema, and also fixed the
example from fixed-regulator to regulator-fixed.

-* PWM beeper device tree bindings
-
-Registers a PWM device as beeper.
-
-Required properties:
-- compatible: should be "pwm-beeper"
-- pwms: phandle to the physical PWM device
-
-Optional properties:
-- amp-supply: phandle to a regulator that acts as an amplifier for the beeper
-- beeper-hz: bell frequency in Hz
-
-Example:
-
-beeper_amp: amplifier {
- compatible = "fixed-regulator";
- gpios = <&gpio0 1 GPIO_ACTIVE_HIGH>;
-};
-
-beeper {
- compatible = "pwm-beeper";
- pwms = <&pwm0>;
- amp-supply = <&beeper_amp>;
-};
