6a3c2aded6 Fix wait loop and void cast (#24) 
* Simplify EINTR/ECANCEL error handling

1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx

* Unify the void cast usage

1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro

e118d99bf5 drivers/power/pm: Historically, the NuttX PM subsystem has consisted of two functional components: (1) an "Upper" part that detects state changes based on a random walk driven by activity levels, and (2) and "lower" part that implementst the state changes. 
This change decouples that upper activity-based logic from the lower random walk logic and allows use of other upper state detection logic (such as a custom, application-specific state machine).
