Default Revert "UBUNTU: SAUCE: Add support for Intellimouse Mode in ALPS touchpad on Dell E2 series Laptops"

BugLink: http://bugs.launchpad.net/bugs/641320

This reverts commit bd79df42218fe1db5e683b567791d4bb97b60685. This
commit seems to have an outdated patch in it and seems to break a number
of touchpads. Reverting for now.
