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
