Input: elantech - add support for newer (August 2013) devices

commit 9cb80b965eaf7af1369f6e16f48a05fbaaccc021 upstream.

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 on an Acer Aspire S7-392-6302.
