These new structs will hold the sleep voltage levels (omap_vc_params) and voltage processor min / max voltages (omap_vp_params.) Previously these were part of the PMIC struct, but they do not really belong there, as they are OMAP chip specific, not PMIC specific parameters. voltdm code is also changed to use the new structs.
