On some platforms, MMIO regions might need slightly different treatment
compared to mapping regular memory; add the notion of MMIO mappings to
the IOMMU API's memory type flags, so that callers can let the IOMMU
drivers know to do the right thing.

Hi all,

Since this is a prerequisite for both MSI remapping and slave DMA
handling to function properly, and the latter still needs some design
work to reach a consensus[1], I thought it worth reposting this
separately from Niklas' series. I've also split it up now that there's
short-descriptor format to cover as well.

Robin.

don't know if it helps in any way but I tested that with my KVM PCIe/MSI
passthrough series for mapping the GICv2m doorbell.
