um: add dummy ioremap and iounmap functions The user mode architecture does not provide ioremap or iounmap, and because of this, the arch won't build when the functions are used in some core libraries. I have designs to use these functions in scatterlist.c where they'd almost certainly never be called on the um architecture but it does need to compile.
