powerpc: export cpu_to_core_id()
Export cpu_to_core_id(). This will be used by the lpfc driver.
This enables topology_core_id() from <linux/topology.h> (defined
to cpu_to_core_id() in arch/powerpc/include/asm/topology.h) to be
used by (non-builtin) modules.
That is arch-neutral, already used by eg, drivers/base/topology.c,
but it is builtin (obj-y in Makefile) thus didn't need the export.
Since the module uses topology_core_id() and this is defined to
cpu_to_core_id(), it needs the export, otherwise:
ERROR: "cpu_to_core_id" [drivers/scsi/lpfc/lpfc.ko] undefined!
Tested on next-20160601.
