[PATCH] Intrepid: bcm5974: BTN_TOUCH event needed for mousedev to work

The mousedev driver requires the use of BTN_TOUCH events to process
ABS_X and ABS_Y events properly, which is what prevents the mouse
from working out-of-the box in Intrepid. This patch adds the BTN_TOUCH
event to bcm5974, and replaces the earlier patch for this bug.
