Log Message:
Fix for PR kern/56613

* For trackpads that report max and min coordinates, retrieve these and
  use them as the boundaries instead of the hard coded limits.
* Drop packets that are have x/y values that are outside the limits of
  the trackpad.  Some trackpads report a stream of low values in some
  situations that cause cursor jumping.
