This series of models added a hardware switch to turn touch
data on/off. To report the state of the switch, SW_TOUCH
is added in include/uapi/linux/input.h.
The driver is also updated to process wireless devices that do
not support touch interface.
Tested-by: Jason Gerecke <killertofu@xxxxxxxxx>

v2: Change SW_TOUCH_ENABLED to SW_TOUCH and clear BTN_TOUCH bit
for button only interfaces as suggested by Peter Hutterer.
