[PATCH] sparsemem: provide pfn_to_nid

Before SPARSEMEM is initialised we cannot provide an efficient pfn_to_nid()
implmentation; before initialisation is complete we use early_pfn_to_nid()
to provide location information.  Until recently there was no non-init user
of this functionality.  Provide a post init pfn_to_nid() implementation.

Note that this implmentation assumes that the pfn passed has been validated
with pfn_valid().  The current single user of this function already has
this check.
