qcom: msm-pm: move cpu status driver register to arch_initcall 



CPU status driver checks whether secondary CPUs are really
powered off or not in the HOTPLUG path. Currently this
driver init being called from the board file. But on newer
targets there are no board files exist. Hence move the driver
registration to arch_initcall level.
