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.
