meta-ampere: mtmitchell: handle overtemp event
Configure gpio monitor to check for OVERTEMP GPIO signals from the Host
CPU. Once the event happens, shutdown the Host to avoid hardware damage
and log a Redfish event log.
Tested:
1. Unplug all FANs and run stress test the Host so that the Temperature
can reach 120C.
2. Check if BMC turns OFF the Host when the CPU Temp reaches 120C.
