Subject: [PATCH] HID: multitouch: Lenovo X1 Tablet Gen3 trackpoint and buttons

One more device that needs 40d5bb87 to resolve regression for the trackpoint
and three mouse buttons on the type cover of the Lenovo X1 Tablet Gen3.

It is probably also needed for the Lenovo X1 Tablet Gen2 with PID 0x60a3
