IOMMU Updates for Linux v3.19

This time with:

* A new IOMMU-API call: iommu_map_sg() to map multiple
non-contiguous pages into an IO address space with only one
API call. This allows certain optimizations in the IOMMU
driver.

* DMAR device hotplug in the Intel VT-d driver. It is now
possible to hotplug the IOMMU itself.

* A new IOMMU driver for the Rockchip ARM platform.

* Couple of cleanups and improvements in the OMAP IOMMU driver.

* Nesting support for the ARM-SMMU driver.

* Various other small cleanups and improvements.

Please note that this time some branches were also pulled into other
trees, like the DRI and the Tegra tree. The VT-d branch was also pulled
into tip/x86/apic.
Some patches for the AMD IOMMUv2 driver are not in the IOMMU tree but
were merged by Andrew (or finally ended up in the DRI tree).
