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.
