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;
