arch: Add pmd_pfn() where it is missing
We need to use this function in common code, so define it for architectures and/or configrations that miss it. The result of pmd_pfn() will only be used if TRANSPARENT_HUGEPAGE is enabled, but a function or macro called pmd_pfn() must be defined, even on machines with two level page tables.
