Input: auo_pixcir_ts - add devicetree support
Add the necessary code to create the needed platformdata from devicetree informations. The interrupt mode of the chip is not set via devicetree, as it is not a property of the hardware but instead only a preferred type of operation. This should probably be made settable via configfs in the future. The option set as default is the mode the datasheet mentions as default.

+* AUO in-cell touchscreen controller using Pixcir sensors
+
+Required properties:
+- compatible: must be "auo,auo_pixcir_ts"
+- reg: I2C address of the chip
+- interrupts: interrupt to which the chip is connected
+- gpios: gpios the chip is connected to
+ first one is the interrupt gpio and second one the reset gpio
+- x-size: horizontal resolution of touchscreen
+- y-size: vertical resolution of touchscreen
+
+Example:
+
+ i2c@00000000 {
+ /* ... */
+
+ auo_pixcir_ts@5c {
+ compatible = "auo,auo_pixcir_ts";
+ reg = <0x5c>;
+ interrupts = <2 0>;
+
+ gpios = <&gpf 2 0 2>, /* INT */
+ <&gpf 5 1 0>; /* RST */
+
+ x-size = <800>;
+ y-size = <600>;
+ };
+
+ /* ... */
+ };
