The "generic" pfn_valid() is only available with CONFIG_SPARSEMEM.
With FLATMEM it's wild west:

$ git grep -w "define pfn_valid" arch/*/include/asm/ | wc -l

This would actually mean that we still need arm64::pfn_valid() for the
FLATMEM case.
SPARSEMEM would be the only memory model going forward.
