iommu/amd: Correct the reported page sizes from the V1 table
The HW only has 52 bits of physical address support, the supported page
sizes should not have bits set beyond this. Further the spec says that the
6th level does not support any "default page size for translation entries"
meaning leafs in the 6th level are not allowed too.
Rework the definition to use GENMASK to build the range of supported pages
from the top of physical to 4k.
Nothing ever uses such large pages, so this is a cosmetic/documentation
improvement only.
