[Impact]
Palm ejection stops working on Elan and Synaptics touchpads with
pointstick.

[Fix]
Re-apply "confidence" quirk on those devices.

[Test]
Move the palm on touchpad, cursor moves too.
With the fix applied, moving palm on touchpad won't move the cursor and
won't generate click events.

[Where problems could occur]
Not that I can think of. Originally these touchpads are working fine
with palm ejection, it's just overlooked when enabling pointsticks.
