[GIT PULL] iommu/io-pgtable: Updates for 4.6

[Will Deacon]

Hi Joerg,

Here are the io-pgtable updates from Robin for 4.6.

The bulk of this is adding support for the ARM v7s page table format,
which will be used by the Mediatek IOMMU driver from Yong Wu. Subsequent
work may also enable this format for the ARM SMMU.

Cheers,

Will
