Some regulators can run on different operating modes (opmodes). This allows systems to choose the most efficient opmode for each regulator. This patch builds on top of (291d761 regulator: Document binding for regulator suspend state for PM state) adding a regulator-initial-mode DT property to configure at startup the operating mode for regulators that support changing its mode during normal operation and a property regulator-mode to be used in the regulator-state-[mem/disk] nodes for 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 binding should define the list of valid operating modes for the regulators found on that device.
