+description:
+ Always On Processor/Resource Power Manager maintains statistics of the SoC
+ sleep modes involving powering down of the rails and oscillator clock.
+
+ Statistics includes SoC sleep mode type, number of times low power mode were
+ entered, time of last entry, time of last exit and accumulated sleep duration.
