IOMMU Updates for Linux v3.6-rc1

The most important part of these updates is the IOMMU groups code
enhancement written by Alex Williamson. It abstracts the problem that a
given hardware IOMMU can't isolate any given device from any other
device (e.g. 32 bit PCI devices can't usually be isolated). Devices that
can't be isolated are grouped together. This code is required for the
upcoming VFIO framework.

Another IOMMU-API change written by be is the introduction of domain
attributes. This makes it easier to handle GART-like IOMMUs with the
IOMMU-API because now the start-address and the size of the domain
address space can be queried.

Besides that there are a few cleanups and fixes for the NVidia Tegra
IOMMU drivers and the reworked init-code for the AMD IOMMU. The later is
from my patch-set to support interrupt remapping. The rest of this
patch-set requires x86 changes which are not mergabe yet. So full
support for interrupt remapping with AMD IOMMUs will come in a future
merge window.
