AMD PI agesawrapper: add PSPP (PCIe Speed Power Policy) interface

PSPP policy is defined in 3rdparty/blobs/pi/amd/*/AGESA.h
    /// PCIe PSPP Power policy
    typedef enum  {
      PsppDisabled,                                           ///< PSPP disabled
      PsppPerformance = 1,                                    ///< Performance
      PsppBalanceHigh,                                        ///< Balance-High
      PsppBalanceLow,                                         ///< Balance-Low
      PsppPowerSaving,                                        ///< Power Saving
      MaxPspp                                                 ///< Max Pspp for boundary check
    } PCIE_PSPP_POLICY;
