Having a CBFS cache scratchpad offers a generic way to decompress CBFS files through the cbfs_map() function without having to reserve a per-file specific memory region. This commit introduces the x86 `PRERAM_CBFS_CACHE_SIZE' Kconfig to set the pre-memory stages CBFS cache size. A cache size of zero disables the CBFS cache feature. The default value is 16 KB which seems a reasonable minimal value enough to satisfy basic needs such as the decompression of a small configuration file. This setting can be adjusted depending on the platform needs and capabilities. We have set this size to zero for all the platforms without enough space in Cache-As-RAM to accommodate the default size.
