meta-ampere: mtjade: handle Tempt events

Handle S0/1 OVERTEMP and S0/1 HIGHTEMP GPIO signals from Host CPU that turn off the Host to
prevent hardware damage and log an event.

Tested:
1. Assert OVERTEMP event by running below command from SCP console:
S0-cli> mww 0x10000f0112d0 0x2
  Check if the Host is turned OFF and event is logged
2. Assert and deassert HIGHTEMP event on Socket 0 and check if new
events are logged.
3. Repeat steps 1 and 2 on Socket 1
