x86/iommu: convert AMD IOMMU code to use new page table allocator

This patch converts the AMD IOMMU code to use the new page table allocator
function. This allows all the free-ing code to be removed (since it is now
handled by the general x86 code) which reduces TLB and cache thrashing as well
as shortening the code.
