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