This header file is created to provide user generic macros for providing regulator supplies and regulator init data. Wrappers are created using these macros which could be used in default scenarios. In other cases, user can use the macros to provide his own configuration information. Wrappers are created only for TWL4030/TPS65950 right now. For other PMICs, they will be added later on.
