dt-bindings: new binding for Ilitek ILI9341 display panels

This adds a new binding for Ilitek ILI9341 display panels. It includes
a compatible string for one display (more can be added in the future).

The YX240QV29-T panel[1] is found, for example, in an Adafruit breakout
board[2] and in Mindsensors' PiStorms[3].

The vendor prefix "adafruit" is used because the actual vendor is not
known, but Adafruit is the most common source for a product that
contains this panel.

		Ilitek ILI9341 display panels

		This binding is for display panels using an Ilitek ILI9341 controller in SPI
		mode.

		Required properties:
		- compatible: "adafruit,yx240qv29", "ilitek,ili9341"
		- dc-gpios: D/C pin
		- reset-gpios: Reset pin

		The node for this driver must be a child node of a SPI controller, hence
		all mandatory properties described in ../spi/spi-bus.txt must be specified.

		Optional properties:
		- rotation: panel rotation in degrees counter clockwise (0,90,180,270)
		- backlight: phandle of the backlight device attached to the panel

		Example:
		display@0{
		compatible = "adafruit,yx240qv29", "ilitek,ili9341";
		reg = <0>;
		spi-max-frequency = <32000000>;
		dc-gpios = <&gpio0 9 GPIO_ACTIVE_HIGH>;
		reset-gpios = <&gpio0 8 GPIO_ACTIVE_HIGH>;
		rotation = <270>;
		backlight = <&backlight>;
		};
