Input: st1232 - add reset pin handling
We add the possibility to hand over a GPIO number for the reset pin. This way we can remove existing board code that takes care of it and group this information properly in the platform data or in the device tree configuration.

+* Sitronix st1232 touchscreen controller
+
+Required properties:
+- compatible: must be "sitronix,st1232"
+- reg: I2C address of the chip
+- interrupts: interrupt to which the chip is connected
+
+Optional properties:
+- gpios: a phandle to the reset GPIO
+
+Example:
+
+ i2c@00000000 {
+ /* ... */
+
+ touchscreen@55 {
+ compatible = "sitronix,st1232";
+ reg = <0x55>;
+ interrupts = <2 0>;
+ gpios = <&gpio1 166 0>;
+ };
