powerpc: Make chip-id information available to userspace
So far "/sys/devices/system/cpu/cpuX/topology/physical_package_id" was always default (-1) on ppc64 architecture. Now, some systems have an ibm,chip-id property in the cpu nodes in the device tree. On these systems, we now use this information to display physical_package_id.
