[GIT PULL] iommu/arm-smmu: Updates for 4.6

[Will Deacon]

Hi Joerg,

Please pull the following arm-smmu updates for 4.6. This lays the
foundations for a functional IOMMU_DOMAIN_DMA for the two drivers,
although we haven't yet thrown the switch since we need to ensure
that the DMA ops all point in the right direction first. Hopefully we'll
get that going for 4.7.
