HID: handle joysticks with large number of buttons
Current HID code doesn't properly handle HID joysticks which have larger number of buttons than what fits into current range reserved for BTN_JOYSTICK. One such joystick reported to not work properly is Saitek X52 Pro Flight System. We can't extend the range to fit more buttons in, because of backwards compatibility reasons. Therefore this patch introduces a new BTN_TRIGGER_HAPPY range, and uses these to map the buttons which are over BTN_JOYSTICK limit.
