Input: synaptics - change min/max quirk table to pnp-id matching
Most of the affected models share pnp-ids for the touchpad. So switching to pnp-ids give us 2 advantages: 1) It shrinks the quirk list 2) It will lower the new quirk addition frequency, ie the recently added W540 quirk would not have been necessary since it uses the same LEN0034 pnp ids as other models already added before it As an added bonus it actually puts the quirk on the actual psmouse, rather then on the machine, which is technically more correct.
