amd-iommu: Fix Guest CR3 Table following c/s 3a7947b6901
"amd-iommu: use a bitfield for DTE" renamed iommu_dte_set_guest_cr3()'s gcr3
parameter to gcr3_mfn but ended up with an off-by-PAGE_SIZE error when
extracting bits from the address.
get_guest_cr3_from_dte() and iommu_dte_set_guest_cr3() are (almost) getters
and setters for the same field, so should live together.
Rename them to dte_{get,set}_gcr3_table() to specifically avoid 'guest_cr3' in
the name. This field actually points to a table in memory containing an array
of guest CR3 values. As these functions are used for different logical
indirections, they shouldn't use gfn/mfn terminology for their parameters.
Switch them to use straight uint64_t full addresses.
