[PATCH] x86_64: Calgary IOMMU - Calgary specific bits
This patch hooks Calgary into the build, the x86-64 IOMMU
initialization paths, and introduces the Calgary specific bits. The
implementation draws inspiration from both PPC (which has support for
the same chip but requires firmware support which we don't have on
x86-64) and gart. Calgary is different from gart in that it support a
translation table per PHB, as opposed to the single gart aperture.
Changes from previous version:
* Addition of boot-time disablement for bus-level translation/isolation
(e.g, enable userspace DMA for things like X)
* Usage of newer IOMMU abstraction functions
