This reverts commit 68b9c5066e39af41d3448abfc887c77ce22dd64d.

Ugh, I really dropped the ball on this one :. So as it turns out RMI4 works perfectly fine on the X1 Extreme Gen 2 except for one thing I didn't notice because I usually use the trackpoint: clicking with the touchpad. Somehow this is broken, in fact we don't even seem to indicate BTN_LEFT as a valid event type for the RMI4 touchpad. And, I don't even see any RMI4 events coming from the touchpad when I press down on it. This only seems to work for PS/2 mode.

Since that means we have a regression, and PS/2 mode seems to work fine for the time being - revert this for now. We'll have to do a more thorough investigation on this.
