Are these new macros valid for both PCI and non-PCI mmio addresses?
The way I understand it, the regular readl/writel family is only
valid for __iomem addresses in PCI BARs, while anything else
has to go through either ioread32/iowrite32 or something arch
specific.

Does this mean we also need an ioread32_releaxed etc?
