Provide a simple driver for GPIO controllable vibrators.
It will be used by the Fairphone 2.

+* GPIO vibrator device tree bindings
+
+Registers a GPIO device as vibrator, where the vibration motor just has the
+capability to turn on or off. If the device is connected to a pwm, you should
+use the pwm-vibrator driver instead.
+
+Required properties:
+- compatible: should contain "gpio-vibrator"
+- enable-gpios: Should contain a GPIO handle
+
+Optional properties:
+- vcc-supply: Phandle for the regulator supplying power
+
+Example from Fairphone 2:
+
+vibrator {
+	compatible = "gpio-vibrator";
+	enable-gpios = <&msmgpio 86 GPIO_ACTIVE_HIGH>;
+	vcc-supply = <&pm8941_l18>;
+};
