[PATCH v3 4/6] mm: don't export memory_add_physaddr_to_nid in arch specific directory

[Jia He <justin.he@xxxxxxx>]

After a general version of __weak memory_add_physaddr_to_nid implemented
and exported , it is no use exporting twice in arch directory even if
e,g, ia64/x86 have their specific version.

This is to suppress the modpost warning:
WARNING: modpost: vmlinux: 'memory_add_physaddr_to_nid' exported twice.
Previous export was in vmlinux
