Drop mention of ISA cards.  Note that I have no idea what to cull from the
supported hardware list.  Judging by the PCI driver attachment, dpt_pci.c
only supports a single adapter rather than the various PCI adapters listed.
The list of EISA adapters listed somewhat overlaps with the device IDs in
dpt_eisa.c.  It's not clear which devices are ISA-only devices.
