Subject: [PATCH] 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;
