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).

drivers/power/pm_activity.c: Add pm_staycount API for get stay numbers. This function is currently not used and a waste of FLASH space.

drivers/power/: PM: Don't update the power state in work thread: (1) Simplify the code logic and remove the work queue dependence, (2) Power calculation is too simple to delay into the work queue

drivers/power: PM: Add pm_stay and pm_relax function so special apps(e.g. mediaplayer) could disable suspend during playback much like linux kernel counterpart

More fixes to problems noted by cppcheck. Some are kind of risky; some are real bugs.
