[PATCH libinput 2/4] Revert "touchpad: only use negative pressure change check on Lenovo *50 and *60 series"

[Peter Hutterer]

We will reinstate the hysteresis for all devices making the negative pressure
check unncessary and thus this commit as well.

This reverts commit 2f5231cc88fccf389a78270d827f6c9201b86794.
