ARM: OMAP2+: Add functions to save and restore powerdomain context The powerdomain control registers are stored in the WKUP powerdomain on AM33XX/AM43XX, which is lost on RTC-only suspend and also hibernate. This adds context save and restore functions for those registers. Sometimes the powerdomain state does not need to change, perhaps we only need to change memory retention states, so make sure the restored state is different from the current state before we wait for a transition.
