Input: xpad - fix for "Mad Catz Street Fighter IV FightPad" controllers

commit be66227151c0cd4da536098c3ee07809101c6faa upstream.

Added MAP_TRIGGERS_TO_BUTTONS for Mad Catz Street Fighter IV FightPad
device. This controller model was already supported by the xpad
driver, but none of the buttons work correctly without this change.

Tested on kernel version 3.9.5.
