hwdb: Add entries for the trackpoint on 2 Thinkpads

Lenovo has changed the sensitivity of the trackpoint on the x240 / T440s / T540
generation of Thinkpads, making them somewhat insensitive by default, add a
hwdb entry to tweak the sensitivity setting.

The ThinkPad X200s is way way too slow by default and unless you push the
trackpoint quite hard only sends delta events in the 1-2 range, tweak the
sensitivity to make it send a wider range of deltas and apply a const accel
factor to make it have a more reasonable speed by default.
