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

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. Cc: [email protected] Signed-off-by: Chen-Yu Tsai <[email protected]> Signed-off-by: Dmitry Torokhov <[email protected]>
