Input: i8042 - add Lenovo LaVie Z to the i8042 reset list
commit 384cf4285b34e08917e3e66603382f2b0c4f6e1b upstream.
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.
