 *   @n@b CSL_pscHwSetup
 *
 *   @b Description
 *   @n It configures the psc registers as per the values passed
 *      in the hardware setup structure.
 *
 *   @b Arguments
 *   @verbatim
            hPsc            Handle to the psc
 
            hwSetup             Pointer to harware setup structure
 
     @endverbatim
 *
 *   <b> Return Value </b>  CSL_Status
 *   @li                    CSL_SOK             - Hardware setup successful
 *   @li                    CSL_ESYS_BADHANDLE  - Invalid handle
 *   @li                    CSL_ESYS_INVPARAMS  - Hardware structure is not
                                                  properly initialized
 *
 *   <b> Pre Condition </b>
 *   @n  None
 *
 *   <b> Post Condition </b>
 *   @n  PSC controller registers are configured according 
 *       to the hardware setup parameters
 *
 *   @b Modifies
 *   @n PSC controller registers
