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
+- 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>;
+};

Need to wrap line.

This should probably be optional. There may not be a s/w controllable
supply.
