libmemifo: x86_64: 16K: No-op PFN APIs

When emulating the page size on a x86_64 device, pagemap
PFN bits are zeroed (not supported) [1] and kernel APIs that
consume PFNs from pagemap are also not available [2].

However we still want to be able to account memory from
libmeminfo (although missing some categorization).

Instead of erroring out, for PFN APIs in libmeminfo return
the the default values (success).
