Philippe Mathieu-Daudé 75cacb128b hw/isa/smc37c669: Change the parallel I/O base to 378H
On the Alpha DP264 machine, the Cirrus VGA is I/O mapped
in the 3C0H-3CFH range, thus I/O base used by the parallel
device clashes, and since a4cb773928 the VGA is not
working:

                                    ^^^                ^^^^^^^^

                   ^^^

      00000801fc0003da-00000801fc0003da (prio 0, i/o): vga
      ...

As there is no particular reason to use this base address
(introduced in 7bea0dd434), change to 378H which is the
default on PC machines.
