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

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).
