Well, scratch that. On second thought, the macro based solution seems to
have more advantages. arch/arm/mach-bcmring/mm.c already has a variant,
but I think I can come up with a more typesafe version that warns if
you pass in an integer for the virtual address of an MT_DEVICE mapping,
or a pointer for a RAM mapping.
