Revert "tablet: don't disable the proximity quirk on good sequences"

Browse source 
This quirk was introduced for #248 was caused by buggy input-wacom drivers,
not by actual firmware, see
https://gitlab.freedesktop.org/libinput/libinput/issues/381#note_279371

This appears to be the only tablet where this fix was needed, but we've been
playing whack-a-mole ever since to work around the various other tablets that
break with this behavior in place.

So let's revert that fix and hope there aren't any other tablets out there
(and if they are, we can probably quirk those). The revert makes the ISDV4 pen
quirk obsolete (see 9cb089f2b6), so this was
folded into this commit.

This reverts commit 4f63345b60.
