Read IO Port data on X86

[Joel Sherrill]

I think you have a mix of RTEMS and non-RTEMS files. RTEMS does
not have a file named io.h. It is rtems/io.h. I really believe that if
you got this far, you are mixing and matching something.

I didn't do any real clean up on the code except to get it to compile
and link. Attached.
