iommu/arm-smmu: misc. driver updates targetting 3.18

Hi all,

This series is a collection of ARM SMMU updates I have in my tree that I'd like to get merged for 3.18. This has mostly come out of the vSMMU work (which is still some way off, as proper testing is proving to be difficult), but Robin has also added minimal support for MMU-401.

There are a couple of other things on my radar (fixing our reporting of IOMMU_CAP_CACHE_COHERENCY and wiring up iommu_group_get_for_dev), but they needn't block sending this series out for review.

Feedback welcome,

Will
