/**
 * Configures the MCBSP using the values passed in the setup structure.
 *
 * <b> Usage Constraints: </b>
 * Both @a CSL_mcbspInit() and @a CSL_mcbspOpen() must be called successfully 
 * in that order before this function can be called. The setup structure
 * consists of the logically grouped sub-structures. The main setup structure
 * as well as these sub-structures must be filled up before calling this
 * function
 *
 * @b Example:
 * @verbatim

     CSL_mcbspHandle hMcbsp;
     CSL_McbspHwSetup hwSetup = CSL_MCBSP_HWSETUP_DEFAULTS;
     ...

     // Init Successfully done
     ...
     // Open Successfully done
     ...
     CSL_mcbspHwSetup(hMcbsp, &hwSetup);
   @endverbatim
 *
 * @return Status of the setup operation
