Input: i8042 - add Lenovo ThinkPad L460 to i8042 reset list

commit b56af54ac78c54a519d82813836f305d7f76ef27 upstream.

Reset i8042 before probing because of insufficient BIOS initialisation of
the i8042 serial controller. This makes Synaptics touchpad detection
possible. Without resetting the Synaptics touchpad is not detected because
there are always NACK messages from AUX port.
