IOMMU Updates for Linux v3.8

A few new features this merge-window. The most important one is
probably, that dma-debug now warns if a dma-handle is not checked with
dma_mapping_error by the device driver. This requires minor changes to
some architectures which make use of dma-debug. Most of these changes
have the respective Acks by the Arch-Maintainers.
Besides that there are updates to the AMD IOMMU driver for refactor the
IOMMU-Groups support and to make sure it does not trigger a hardware
erratum.
The OMAP changes (for which I pulled in a branch from Tony Lindgren's
tree) have a conflict in linux-next with the arm-soc tree. The conflict
is in the file arch/arm/mach-omap2/clock44xx_data.c which is deleted in
the arm-soc tree. It is safe to delete the file too so solve the
conflict. Similar changes are done in the arm-soc tree in the common
clock framework migration. A missing hunk from the patch in the IOMMU
tree will be submitted as a seperate patch when the merge-window is
closed.

ARM: ixp4xx bug fixes

These were originally prepared by Krzysztof Halasa but not submitted
in time for v3.7 due to some confusion about how ixp4xx patches should
be handled. Jason Cooper thankfully offered to help out sending the
patches upstream through arm-soc now, but given the timing, we could
as well delay them for 3.8.
