Krzysztof: given this, I think it would be fair to add an enum to the
driver to keep track of the actual hardware type (grouped into probably
just 3, S3C24XX, S3C6400, APPLE), get rid of any code in there that
cares about the uapi-visible port type (other than setting it correctly
for those that do exist, to maintain current behavior), and just make
everything else use PORT_8250 for that?
