iommu: Tidy up io-pgtable dependencies
Some io-pgtable implementations, and thus their users too, carry a
slightly odd dependency to get around the GENERIC_ATOMIC64 version of
cmpxchg64() often failing to compile. Since this is a functional
dependency, it's a bit misleading and untidy to tie it explicitly to
COMPILE_TEST while assuming that it's also implied by the other
platform/architecture options. Make things clearer by separating these
functional dependencies into distinct statements from those controlling
visibility, and since they do look a bit non-obvious to the uninitiated,
also commenting them for good measure.
