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 vendor prefix "noname" is used because the vendor is not known. The YX240QV29-T panel[1] is found, for example, in an Adafruit breakout board[2] and in Mindsensors' PiStorms[3].
