Subject: [PATCH 01/21] ARM: topology: export cpu_topology

The cpu_topology symbol is required by any driver using the topology
interfaces, which leads to a couple of build errors:

ERROR: "cpu_topology" [drivers/net/ethernet/sfc/sfc.ko] undefined!
ERROR: "cpu_topology" [drivers/cpufreq/arm_big_little.ko] undefined!
ERROR: "cpu_topology" [drivers/block/mtip32xx/mtip32xx.ko] undefined!

The obvious solution is to export this symbol.
