[PATCH] Switch s390 to NO_IOMEM

So we'll just need to replace NO_IOPORT with NO_IOMEM in Kconfig and
kill arch/s390/mm/ioremap.c.

BTW, there's an annoying bit of junk in there - IO_SPACE_LIMIT.  We
only need it for /proc/ioports, which AFAICS shouldn't even be there
on s390 (or uml).  OTOH, removing that thing would mean a user-visible
change - we go from "empty file in /proc" to "no such file in /proc"...
