HID: ntrig: Remove unused macro, TripleTap and QuadTap
Removing the higher number taps. Their usage was incorrect and even if correct they should not be used for a touch screen. _MT_ events should be used to communicate multiple fingers. Signed-off-by: Rafi Rubin <rafi@seas.upenn.edu> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
