Kernel cannot bring up Non-boot cpus always get "Processor xx is stuck".
this issue bring by http://patchwork.ozlabs.org/patch/418912/ (powerpc:
Secondary CPUs must set cpu_callin_map after setting active and online)
We need to take timebase after bootup cpu give the timebase firstly.

When start_secondary, non-boot cpus set cpu_callin_map for boot cpu
after that boot cpu will give the timebase for non-boot cpu. Otherwise
non-boot cpus will fall in dead loop to waiting bootup cpu to give
imebase.
