[PATCH 1/3] powerpc: export cpu_to_chip_id

[Vladimir Murzin]

While cross-building for PPC64 I've got

ERROR: ".cpu_to_chip_id" [drivers/block/mtip32xx/mtip32xx.ko] undefined!

mtip32xx refer to topology_physical_package_id, which stands for
cpu_to_chip-id.

Make cpu_to_chip-id (and topology_physical_package_id) available for
external users.
