Prodded by Yongari, add support for Holtek HT80232. Add the device

ID, plus the ability to force '16-bit mode' which really means NE-2000
mode.  Other open source drivers suggest that the Holtek misbehaves if
you allow the 8-bit probe.  Also, all of the PCI chips emulate
NE-2000ish cards, so always force 16-bit mode for memory transfers.
