[pull-request][Precise] Support for additional ALPS touchpads

[Seth Forshee]

Dmitry Torokhov has merged my ALPS touchpad patches into the input
subsystem linux-next branch, so barring any catastrophic discoveries
they ought to be in their final upstream form. The patches that Dmitry
merged apply cleanly to 3.2-rc1, and now that precise master-next has
been rebased I think it's a good time to pick them up and drop the
IMPS/2 sauce patches we've been carrying. I've included reverts for the
IMPS/2 patches in the pull request.

The following changes since commit c071ab780fe4bdf6fffcd3f8f73aadddd9c831c5:
