power: Rework OS <-> Application interface This commit simplifies OS <-> Application interface controlling power management. In the previous approach application-based PM required overriding sys_suspend() and sys_resume() functions. As these functions actually implemented power state change, in such case application basically had to provide own implementation of all PM-related stuff, which was not portable and hard to maintain. This commit changes this scheme: The sys_suspend() and sys_resume() are now system functions while the application could either use built-in power management policies or provide its own. All details of power mode switching are now handled by the OS. Also, this commit cleans up the Kconfig options related to system-level power management grouping them under common CONFIG_SYS_PM_ prefix. Signed-off-by: Piotr Zięcik <piotr.ziecik@nordicsemi.no>

power: Add device idle power management support Add framework for device Idle Power Management(IPM) for suspending devices based on device idle. This will help in saving power even while system(CPU) is active. The framework uses device_set_power_state() API set the device power state accordingly based on the usage count.

Enable device Idle Power Management to save power.
With device Idle PM enabled, devices can be suspended or
resumed based on the device usage even while the CPU or
system is running.

logging: Refactor LOG_MODULE_REGISTER and LOG_MODULE_DECLARE macros Changed LOG_MODULE_REGISTER and LOG_MODULE_DECLARE macros to take log level as optional parameter. LOG_MODULE_DECLARE can now also be used in static inline functions in headers. Added LOG_LEVEL_SET macro which is used when instance logging API is used to indicate maximal log level compiled into the file.
