2022-03-15{mb, soc}: Move mrc_cache invalidating logic into `memory` common codeSubrata Banik
Commit hash b8b40964 ( mb, soc: Add the SPD_CACHE_ENABLE) introduced per mainboard logic to invalidate the mrc_cache. This patch moves mrc_cache invalidating logic into IA common code and cleans up the code to remove unused argument `dimms_changed` from SoC and mainboard directory.

2022-03-02mb, soc: Add the SPD_CACHE_ENABLEZhuohao Lee
In order to cache the spd data which reads from the memory module, we add SPD_CACHE_ENABLE option to enable the cache for the spd data. If this option is enabled, the RW_SPD_CACHE region needs to be added to the flash layout for caching the data. Since the user may remove the memory module after the bios caching the data, we need to add the invalidate flag to invalidate the mrc cache. Otherwise, the bios will use the mrc cache and can make the device malfunction. BUG=b:200243989 BRANCH=firmware-brya-14505.B TEST=build pass and enable this feature to the brask the device could speed up around 150ms with this feature.
