sh: fix build error by adding generic ioport_{map/unmap}()

Browse Source 
Fix build error as reported by Geert Uytterhoeven here:

  http://kisskb.ellerman.id.au/kisskb/buildresult/11607865/

The error happens when CONFIG_HAS_IOPORT_MAP=n because of which there
are missing definitions of ioport_map/unmap().  Fix this build error by
adding these prototypes.
