-Device-Tree binding for ps/2 gpio device

-Required properties:
-	- compatible = "ps2-gpio"
-	- data-gpios: the data pin
-	- clk-gpios: the clock pin
-	- interrupts: Should trigger on the falling edge of the clock line.
-
-Optional properties:
-	- write-enable: Indicates whether write function is provided
-	to serio device. Possibly providing the write fn will not work, because
-	of the tough timing requirements.

-Example nodes:

-	compatible = "ps2-gpio";
-	interrupt-parent = <&gpio>;
-	interrupts = <23 IRQ_TYPE_EDGE_FALLING>;
-	data-gpios = <&gpio 24 GPIO_ACTIVE_HIGH>;
-	clk-gpios = <&gpio 23 GPIO_ACTIVE_HIGH>;
-	write-enable;
