quirks: Thinkpad T470 trackpoint multiplier
Set multiplier for T470 to 0.4, same as for T480.
Trackpoint behavior on T470 was good before 1.9.0 (more precisely,
before the commit 87b568) when a new trackpoint acceleration algorithm
was introduced instead of the traditional linear filter. Since then
it is too sensitive and seems impossible to fine-tune using hw settings
or libinput accel speed setting.
With multiplier set to 0.4 it is as good (or better) as in 1.8.4.
Sensitivity feels the same as in 1.8.4 with the same hw settings for
speed and sensitivity.
