mb, soc: Add the SPD_CACHE_ENABLE

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.
