HID: add multi-input quirk for NextWindow Touchscreen.

commit 9db630b48a99adb4156e205b812fba8959644280 upstream.

These touchscreens are mounted onto HP TouchSmart and the Dell Studio One
19. Without a quirk they report a wrong button set and the x/y coordinates
through ABS_Z/ABS_RX, confusing the higher levels (most notably X.Org's
evdev driver).

Device id 0x003 covers models 1900, 2150, and 2700 [1] though testing could
only be performed on a model 1900.
