Subject: [PATCH 09/12] MIPS: bmips: Switch to new topology interface

Change the parameter of cpu_set_core from cpudata to cpuid.
Also set cluster id for bmips as it have different method to probe
actual hwid of CPU, and smp_store_cpuinfo is using cluster id to
determine if we should probe topology info again.
