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>;
};
