[PATCH v7 1/5] dt-bindings: Introduce SoC sleep stats bindings

[Maulik Shah]

From: Mahesh Sivasubramanian <msivasub@codeaurora.org>

Add device binding documentation for Qualcomm Technologies, Inc. (QTI)
SoC sleep stats driver. The driver is used for displaying SoC sleep
statistic maintained by Always On Processor or Resource Power Manager.

+  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.
