On Monza, the lift frame can report these for *multiple contacts* without an id or a slot, which is super-duper invalid -_-".
(And we have ABS_MT_POSITION_X & ABS_MT_POSITION_Y for the "saner" frames, plus these devices generally don't support pens, so we don't make use of pressure).
(Also, switched to a dedicated handler like for the phoenix quirks, to avoid bogging down the standard handler with hacks for broken drivers).
