ia64: export memory_add_physaddr_to_nid to fix cxl build error 

[ Upstream commit 97c318bfbe ]

cxl_pmem.ko uses memory_add_physaddr_to_nid() but ia64 does not export it,
so this causes a build error:

ERROR: modpost: "memory_add_physaddr_to_nid" [drivers/cxl/cxl_pmem.ko] undefined!

Fix this by exporting that function.
