Input: usbtouchscreen - add support for Data Modul EasyTouch TP 72037

The Data Modul TP 72037 EasyTouch controller is derived from EGALAX
controller and is capable of detecting dual contacts. Packets can be 5
bytes or 10 bytes long, depending whether one or two contacts are
detected. Format is same as EGALAX touch controller, but with x and y
coordinates inverted.

Say Y here if you have a EasyTouch USB Touch controller device support.
If unsure, say N.
