meta-facebook: greatlakes: System state initialization
Description:
- System state initialization.
Design:
- Use script to determine 12V and host current state
12V: use BMC gpio
host: Use BIC gpio
- Set correct state on CurrentHostState property for host status
- Set correcr state on CurrentPowerState property for 12V status
Test Case:
1. 12V on and host off
2. 12V on and host on
3. 12V off and host off
