Input: i8042 - add Lenovo XiaoXin Air 12 to i8042 nomux list



commit 17d51429da722cd8fc77a365a112f008abf4f8b3 upstream.

This fixes two finger trackpad scroll on the Lenovo XiaoXin Air 12.
Without nomux, the trackpad behaves as if only one finger is present and
moves the cursor when trying to scroll.
