cgd d77d6869b1 add a driver for "PCI 'universal' communications" cards, that is, PCI cards
which contain 'standard' com- and lpt-type ports.  Some of these present
as PCI simple-communications/serial or simple-communications/parallel
devices, but many do not.  (Additionally, there is no document that I can
find that describes the "specific well-konwn register-level" description
of how the 'standard' devices' config space headers shold work.)  Eventually,
some of the devices driven by this code should become simple pci attachments
for the 'lpt' and 'com' drivers, but that requires solid documentation.
