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.
