Vasant Hegde 11c439a194 iommu/amd/pgtbl_v2: Fix domain max address ...

IOMMU v2 page table supports 4 level (47 bit) or 5 level (56 bit) virtual
address space. Current code assumes it can support 64bit IOVA address
space. If IOVA allocator allocates virtual address > 47/56 bit (depending
on page table level) then it will do wrong mapping and cause invalid
translation.

Hence adjust aperture size to use max address supported by the page table.
