jonathan 874baa6c95 Rewrite dc7085 (dz-11 clone) driver as MI back-end, with bus-specific
cfattach front-end code:
  dc_ds for the decstation 2100( pmin), 3100 (pmax), and 5100.
  dc_ioasic for the decstation 5000/200 (3max) which does  not have a
  DEC TC-style IOCTL asic, but is configured as if it did.

* Add pre-autoconfig  code initialization of kerenl dc driver console I/O
  for remote serial consoles.  The hack to use PROM serial I/O until the
  dc device is autoconfigured is no longer necessary.
