Input: i8042 - add Lenovo LaVie Z to the i8042 reset list

Browse source 
The Lenovo LaVie Z laptop requires i8042 to be reset in order to
consistently detect its Elantech touchpad. The nomux and kbdreset
quirks are not sufficient.

It's possible the other LaVie Z models from NEC require this as well.
