Log Message:
Fix a couple of problems with MII-equipped NE2000 derivatives reported by
Björn Johannesson on current-users@:

- Re-factor dp8390_stop() into dp8390_halt() (that does the stuff to
  halt the hardware) and dp8390_stop() (which alls dp8390_halt() before
  calling mii_down() via sc->sc_stop_card()).  This prevents us from
  calling mii_down() before all of the interface data structures have
  been set up, which these days can trip a KASSERT().

- Add a 1-second timer to call mii_tick(), and enable it in the
  sc->sc_init_card() callback, and cancel it in the sc->sc_stop_card()
  and sc->sc_media_fini() callbacks.  This is actually a long-standing
  bug that previously didn't have much practical effect, but causes
  problems with dhcpcd's link live-ness detection logic.
