I just saw that we already have an option like that, with a slightly different name.
arch/s390/Kconfig contains
config NO_IOMEM def_bool y
and lib/Kconfig contains
config HAS_IOMEM boolean depends on !NO_IOMEM default y
You should probably just use one of these two to disable any driver that uses ioremap or similar.
