Call Redfish override protocol to notify platform that the Redfish
changes system settings and about to perform system reboot. Platform
firmware can do platform specific operation before system rebooted.
To follow platform policy, platform can reject system reboot by
returning error status and Redfish feature core driver will abort system
reboot.
