Alexander Shiyan 976358e234 Input: add a new driver for GPIO beeper
This patch adds a new driver for the beeper controlled via GPIO pin.
The driver does not depend on the architecture and is positioned as
a replacement for the specific drivers that are used for this function.

* GPIO beeper device tree bindings
Register a beeper connected to GPIO pin.
Required properties:
- compatible: Should be "gpio-beeper".
- gpios: From common gpio binding; gpio connection to beeper enable pin.
Example:
beeper: beeper {
compatible = "gpio-beeper";
gpios = <&gpio3 23 GPIO_ACTIVE_HIGH>;
};
