This concludes the list of older drivers I had from earlier after working
on the timeout(9) -> callout(9) changes (almost finished with that, just
a few things left to test changes for, one of them being fail points before
we can remove timeout()/untimeout() entirely).

I do not have plans for removing any other drivers, though am open to
suggestions.  Some possibilities include:

- tty drivers that haven't been updated to new tty and have been disconnected
  from the build since 8.0 including digi(4) and cy(4).  I know Bruce has
  patches for sio(4) that I just haven't merged, so I'm inclined to leave
  sio(4), but the other disconnected drivers are candidates I think.
- Older storage adapters:
  - aha (ISA)
  - ahb (EISA)
  - adv (ISA / EISA / PCI)
  - adw (PCI)?
  - bt (ISA / EISA / PCI)
  - aic (ISA / PCCard)
  - ct (ISA / CBUS)
  - dpt (ISA / EISA / PCI)
  - ncv (PCCard / PCI)
  - nsp (PCCard)
  - stg (ISA / PCCard / PCI)
  (Note: some of these are PC-98 related and might remove too much of the
   PC-98 ecosystem if removed?)
- mse(4) (ISA-only non-PS-2, non-serial mouse)
- joy(4) (ISA-only, was on various Sound Cards, etc., but I haven't seen
  a "game port" on a modern box in a long while)
