powerpc/smp: Use cpu_to_chip_id() to find core siblings
When building the CPU scheduler topology the kernel uses the ibm,chipid property from the devicetree to group logical CPUs. Currently the DT search for this property is open-coded in smp.c and this functionality is a duplication of what's in cpu_to_chip_id() already. This patch removes the existing search in favor of that. It's worth mentioning that the semantics of the search are different in cpu_to_chip_id(). When there is no ibm,chipid in the CPUs node it will also search /cpus and / for the property, but this should not effect the output topology.
