SLW: Use wakeup_engine state to handle errors in wakeup engine
Patch introduces wakeup_engine_state which replaces a bool
has_wakeup_engine. wakeup_engine_state can have 3 states :
- WAKEUP_ENGINE_PRESENT : When everything is good.
- WAKEUP_ENGINE_NOT_PRESENT : When wakeup_engine is not correctly detected.
- WAKEUP_ENGINE_FAILED : If any operation on wakeup_engine failed.
