The production batch of Lichee Pi Zero board features a NS2009 resistive
touchscreen controller, which is wired to touch panel pins at 40-pin LCD
connector, in order to make the board fully compatible to 40-pin LCDs
with resistive touch panel which are used with Lichee Pi One (with A13's
integrated resistive touch controller).

Add the device node for the touchscreen controller.
