meta-ampere: power control: refactor host power control
Refactor the Mt.Jade Host power control operations to support Altra
CPU following the Altra SoC BMC Interface specification which still
satisfying the OpenBMC power control framework.
Tested: check the below cases and ensure Host state report correctly:
1. Run "reboot" from Host Linux. Check the Host is graceful
shutdown, then SYS_RESET is asserted and the Host is booted.
2. Run "shutdown" from Host Linux. Check the Host is graceful
shutdown then the chassis power is turned OFF.
3. Run "ipmitool chassis power soft". Check the Host is graceful
shutdown
4. Execute Redfish GracefulShutdown. Check the Host is graceful
shutdown then the chassis power is turned OFF.
5. Execute Redfish GracefulRestart. Check the Host is graceful
shutdown then turned ON.
6. Check other IPMI chassis power and Redfish Reset actions work.
