Subject: [PATCH 2/5] Input: add BTN_TOUCH event

From: Mike Rapoport <mike@...pulab.co.il>

Add BTN_TOUCH event reporting to ucb1400_ts and accelerated mainstone-wm97xx
touchscreen drivers. Together with previously posted similar patch for
wm97xx-core this will make all touchscreen drivers behave consistently wrt.
BTN_TOUCH.
