iommu/amd: Narrow the use of struct protection_domain to invalidation

Browse source

The AMD io_pgtable stuff doesn't implement the tlb ops callbacks, instead
it invokes the invalidation ops directly on the struct protection_domain.

Narrow the use of struct protection_domain to only those few code paths.
Make everything else properly use struct amd_io_pgtable through the call
chains, which is the correct modular type for an io-pgtable module.
