touchpad: restore the hysteresis by default
A large part of the bugs seen right now are related to touchpads jittering too much. Fixing them one by one is entertaining, but time consuming. Right now the number of touchpads that require a hysteresis seem to outnumber those that don't, so switch the approach around: leave the hysteresis in place but disable it for those touchpads that don't need it.
