src/lib: Add Kconfig option for SPD cache in FMAP
Currently, the option to cache DIMM SPD data in an FMAP region
is closely coupled to a single board (google/hatch) and requires
a custom FMAP to utilize.
Loosen this coupling by introducing a Kconfig option which adds
a correctly sized and aligned RW_SPD_CACHE region to the default FMAP.
Add a Kconfig option for the region name, replacing the existing hard-
coded instance in spd_cache.h. Change the inclusion of spd_cache.c to
use this new Kconfig, rather than the board-specific one currently used.
Lastly, have google/hatch select the new Kconfig when appropriate to
ensure no change in current functionality.
Test: build/boot WYVERN google/hatch variant with default FMAP, verify
FMAP contains RW_SPD_CACHE, verify SPD cache used via cbmem log.
Also tested on an out-of-tree Purism board.
