s390 gained IOMEM support when they started having PCI attachments.
arch/score selects NO_IOMEM, though they do in fact use MMIO, and
I'm sure their architecture has lots of other problems with build
testing that nobody cares about.
arch/tile can select NO_IOMEM when PCI is disabled, they might
care about this, though I think they also have other build-time
issues.

That sounds fine with me as well.
