hooks: Introduce HOOK_CHIPSET_SHUTDOWN_COMPLETE
A new hook HOOK_CHIPSET_SHUTDOWN_COMPLETE is introduced, which are
called from the chipset task, while the system has already shut down
and all the suspend rails are already off.
It will be used for executing pending EC reboot at the chipset shutdown.
The EC reboot should be executed when the chipset is completely off.
