IOMMU Updates for Linux v4.7

The updates include:

* Rate limiting for the VT-d fault handler

* Remove statistics code from the AMD IOMMU driver. It is unused
and should be replaced by something more generic if needed

* Per-domain pagesize-bitmaps in IOMMU core code to support
systems with different types of IOMMUs

* Support for ACPI devices in the AMD IOMMU driver

* 4GB mode support for Mediatek IOMMU driver

* ARM-SMMU updates from Will Deacon:

- 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

* Various fixes here and there
