/**
* @brief Notify exit from kernel idling after PM operations
*
* This function would notify exit from kernel idling if a corresponding
* pm_system_suspend() notification was handled and did not return
* PM_STATE_ACTIVE.
*
* This function would be called from the ISR context of the event
* that caused the exit from kernel idling. This will be called immediately
* after interrupts are enabled. This is called to give a chance to do
* any operations before the kernel would switch tasks or processes nested
* interrupts. This is required for cpu low power states that would require
* interrupts to be enabled while entering low power states. e.g. C1 in x86. In
* those cases, the ISR would be invoked immediately after the event wakes up
* the CPU, before code following the CPU wait, gets a chance to execute. This
* can be ignored if no operation needs to be done at the wake event
* notification. Alternatively pm_idle_exit_notification_disable() can
* be called in pm_system_suspend to disable this notification.
