[PATCH] rio driver rework continued #1

More header cleanups, strip out typedefs and remove cruft.  There are a lot of
magic macros that can go and also a great deal of abuse of volatile that is
not needed any more as this patch set cleans up the misuse of pointer access
to ISA and PCI space.

It now builds cleanly on 64bit, although there is more work left to do
