This patch series adds IOMMU protocol and updates the consumer
to support IOMMU based DMA access in UEFI.

This patch series can support the BmDmaLib request for AMD SEV.
submitted by Duran, Leo <leo.duran@amd.com> and Brijesh Singh <brijesh.ksingh@gmail.com>.
https://lists.01.org/pipermail/edk2-devel/2017-March/008109.html, and
https://lists.01.org/pipermail/edk2-devel/2017-March/008820.html.
We can have an AMD SEV specific IOMMU driver to produce IOMMU protocol,
and clear SEV in IOMMU->SetAttribute().

This patch series can also support Intel VTd based DMA protection,
requested by Jiewen Yao <jiewen.yao@intel.com>, discussed in
https://lists.01.org/pipermail/edk2-devel/2017-March/008157.html.
We can have an Intel VTd specific IOMMU driver to produce IOMMU protocol,
and update VTd engine to grant or deny access in IOMMU->SetAttribute().

This patch series does not provide a full Intel VTd driver, which
will be provide in other patch in the future.

The purpose of this patch series to review if this IOMMU protocol design
can meet all DMA access and management requirement.
