Add support for the Flatfrog Multitouch 3200 panel. This panel
advertises some fields that it does not use, hence the new quirk.

The Flatfrog team pointed out that the pressure information, which is
currently present but set to a fixed value, is a scheduled firmware
update. Therefore, ignoring the pressure information seems
unnecessary, and I agree. This version is without the pressure quirk,
and will be pushed to the maybe branch in a couple of days.
Thanks,
Henrik
