regulator: Add mode mapping function to struct regulator_desc
The "regulator-initial-mode" and "regulator-mode" DT properties allows to configure the regulator operating modes at startup or when a system enters into a susend state. But these properties use as valid values the operating modes supported by each device while the core deals with the standard operating modes. So a mapping function is needed to translate from the hardware specific modes to the standard ones. This mapping is a non-varying configuration for each regulator, so add a function pointer to struct regulator_desc that will allow drivers to define their callback to do the modes translation.
