Removing vpo driver

[Warner Losh]

Greetings,

Unless there's a concrete objection, and some indication it has been used
in FreeBSD 12 or later, I plan on removing it after FOSDEM sometime.

This driver is for the ZIP100 drive (the 100MB floppy) connected via a
parallel port. This hasn't been relevant for 20 years since the industry
has moved on. The umass driver supports the USB version of the ZIP100 drive
and I used last summer to recover a dozen zip discs for a friend. This
provides a migration path for those that may need it for $15-$25 on ebay
depending on your luck.

Given the lack of changes to this drive, and the massive changes in the
system since it was written, I'd be greatly surprised if it still worked on
relevant hardware.

Comments?

P.S.  https://reviews.freebsd.org/D23389 has the proposed changes.
