Just a drive by comment, but IMO we should just get rid of HAS_IOMEM
altogether. It is really just a !UML option as I think every other
arch enables it. If folks really want to disable drivers on UML, just
disable the subsystems.

Though now with kunit mocking, there's a desire to enable HAS_IOMEM on UML, too.
