[GIT PULL] iommu: IOMMU_PRIV support for 4.11

[Will Deacon]

Hi Joerg,

Please pull the following IOMMU changes for 4.11. These patches from
Sricharan add support for "privileged" IOMMU mappings, which are useful
with master devices that support transactions at different privilege
levels and want to control the permissions independently.

Cheers,

Will
