Its already the case. Hotplug CPU restarts just like CPU bring-up.
Initial code, hotplug cpu and last cpu(suspend) were taking identical
path for the suspend wakeup. Later you suggested after the discussion
that hotplug CPU state need not be saved and can be restarted just like
the CPU bring-up path.

So the current code follows above.
