[Aaron Ma]

BugLink: https://bugs.launchpad.net/bugs/1733605

[Impact]
Elantech touchpad on Lenovo laptops L480/580 report it's version as 15,
and current kernel can not support this hw_version,
so driver didn't support horizontal,vertical and multi-touch.
error log:
kernel: psmouse serio1: elantech: unknown hardware version, aborting...

[Fix]
Add the ictype as hw_version 4 to support this new touchpad.

[Test Case]
Tested on Lenovo L480/580, touchpad/trackstick works fine, multi-touch
ok.

[Regression Potential]
Add new ictype of on specific touchpad, no regression is supposed.
