Some regulators can run on different operating modes (opmodes). This allows systems to choose the most efficient opmode for each regulator. This patch adds a "regulator-initial-mode" property to configure at startup the operating mode for the regulators that support changing its mode during normal operation and a "regulator-mode" to be used as a property of the suspend states "regulator-state-[mem/disk]" nodes for the regulators that supports changing its operating mode when the system enters in a suspend state. The set of possible modes that a regulator can operate depends on the hardware capabilities so a list of generic operating modes can't be provided. Instead, each hardware should define the list of valid operating modes for the regulators found on that device.
