[GIT PULL] iommu/arm-smmu: Updates for 4.7

[Will Deacon]

Hi Joerg,

Please pull the following arm-smmu updates for 4.7. The highlights are:

  * Support for 64k pages with SMMUv1 implementations (e.g MMU-401)
  * Remove open-coded 64-bit MMIO accessors
  * Initial support for 16-bit VMIDs, as supported by some ThunderX
    SMMU implementations
  * A couple of errata workarounds for silicon in the field

As a result of the MMIO accessor rework, there is an asm-generic change
here, but it has been Acked-by Arnd.

Thanks,

Will
