    intel sandy/ivy: Skip SPD loading on S3 resume path
    
    For S3 resume path SPD is only used for DIMM replacement detection.
    As this detection already fails in the case of removal/insertion of
    same DIMM, we can rely on cbmem_recovery() failure alone to force
    system reset in case someone accidentally does DIMM replacements while
    system is suspend-to-ram stage.
    
    Skipping DIMM replacement detection allows skipping slow SPD loading,
    thus reducing S3 resume path time by 80ms for every installed DIMM.
