Added detection for newer Elantech touchpads, so that kernel doesn't
fall-back to default PS/2 driver. Supports touchpads released after
~August 2013.  Fixes bug:
https://lists.launchpad.net/kernel-packages/msg18481.html

Tested-by: Matt Walker <matt.g.d.walker-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> on an Acer Aspire S7-392-6302
