PM / AVS: SmartReflex: use omap_sr * for minmax interfaces
SmartReflex driver interface is natively divided to two parts: - external SmartReflex interface - interface between SmartReflex driver and SmartReflex Class Functions which belong to AVS class interface can use struct omap_sr* instead of struct voltatedomain*, to provide a direct connection between SR driver and SR class. This allows us to optimize and not do additional lookups where none is required. sr_configure_minmax() is interface function between SR driver and SR class. It is typically used by Class driver to configure MINMAXAVG module inside SmartReflex module. Now it takes struct omap_sr* as input parameter.
