MIPS: SMP_CPS: Switch to hotplug core state synchronization
Switch to the CPU hotplug core state tracking and synchronization
mechanim. This unfortunately requires to add dead reporting to the non CPS
platforms as CPS is the only user, but it allows an overall consolidation
of this functionality.
No functional change intended.
