Back when ioread was being discussed on linux-arch, I remember Linus
saying that perhaps *all* ioreads should be relaxed wrt. DMA (unlike the
current mmio accessor functions), but I'm not sure if those are the
semantics we finally settled on. If not, an ioread*_relaxed would be
nice to add for the platforms that can support it.
