add a sg_dma backend for amd64 bus_dma. This is a lot more clever about
mapping to the gart than the old code, and shouldn't conflict with
bouncebuffers when they're added.
This is essentially the sparc64 iommu code that's been modularised a bit
so I can eventually use the same code for agp-based dma for memory
managed drm drivers.
Now, this would overflow ramdiskA, so iommu and sg_dma are now #ifndef
SMALL_KERNEL.
ok kettenis@, marco@. SMALL_KERNEL discussions with deraadt.
