mb/purism/librem_cnl: Use FMAP-based SPD cache
Use a FMAP region to cache SPD data, providing improvements in boot time and detection of change in DIMM population (which FSP will sometimes fail to detect / fail to invalidate the MRC cache). Adapted from implementation used in google/hatch. Test: build/boot Librem Mini v2, verify SPD cache used, changes in DIMM population properly detected.
