meta-ampere: mtmitchell: handle power sequence failure

This commit supports log the power on sequence to analyze power on
failure. This would include:
- PSU power good monitoring to indicate PSU is powered on.
- System power good monitoring to indicate CPU is powered on.

Tested:
1. Power on Host, check the Event logs identify the system
   /redfish/v1/Systems/system/LogServices/EventLog/Entries
   "Message": "Host firmware boots with 1 Processor",
2. Check the Event logs in case power on failure.
