Like many other recent thinkpads the factory default pointingstick
sensitivity on these devices is quite low, making the pointingstick
very slow in moving the cursor.
This extends the existing hwdb rules for tweaking the sensitivity to
also apply to the X1 carbon 4thgen model.

Like the T440s these need the sensitity to be set significantly higher
then the default of 128 for the trackpoint to be usable. Like with the
T440s 200 seems to be a good value to get a reasonable but not too high
sensitivity.
The pointingstick of the Dell Latitude E6400 is somewhat slow by default,
whereas the pointingstick of the Dell Latitude D620 is much too fast by
default, set POINTINGSTICK_CONST_ACCEL for both of them to adjust for this.
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.
IBM / Lenovo trackpoints allow specifying a sensitivity setting through a
ps/2 command, which changes the range of the deltas sent when using the
trackpoint.
On some models with normal usage only deltas of 1 or 2 are send, resulting in
there only being 2 mouse cursor movement speeds, rather than the expected fluid
scale. Changing the sensitivity to a higher level than the bootup default fixes
this.
This commit adds support for setting a POINTINGSTICK_SENSITIVITY value
in hwdb to allow changing the sensitivity on boot through udev / hwdb.
There is quite a wide spread in the delta events generated by pointingsticks,
some generate deltas of 1-2 under normal use, while others generate deltas
from 1-20.
This commit adds a hwdb file which allows specifying a per model
POINTINGSTICK_CONST_ACCEL value which can be used by the userspace input stack
to normalize the deltas so that all pointingsticks get the same feeling ootb.
The hwdb matching re-uses the existing 60-evdev.rules.
