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).

Select this (or let it be auto-selected by not defining any cache

sizes) in order to allow U-Boot to automatically detect the sizes

of caches at runtime. This has a small cost in code size & runtime
|

so if you know the cache configuration for your system at compile

|
time it would be beneficial to configure it.
