[PATCH] Switch s390 to NO_IOMEM

"s390 does not even need (in|out)b(_p|). I wondered what else from
io.h do we not need. The answer is: almost nothing. With the devres
patch from Al and the dma-mapping patch from Heiko we can get rid of
iomem and all associated definitions."
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"...
