Subject: [PATCH -next] drivers/base/arch_topology.c: remove superfluous header

arch_topology.c hasn't use any macro or function declared in linux/percpu.h,
linux/smp.h and linux/string.h.
Thus, these files can be removed from arch_topology.c safely without
affecting the compilation of the drivers/base/ module
