Move details of the L1 cache line sizes & total sizes into Kconfig, defaulting to 0. A new CONFIG_SYS_CACHE_SIZE_AUTO Kconfig entry is introduced to allow platforms to select auto-detection of cache sizes, and it defaults to being enabled if none of the cache sizes are set by the configuration (ie. sizes are all the default 0), and code is adjusted to #ifdef on that rather than on the definition of the sizes (which will always be defined even if 0).
