[U-Boot] SYS_HAVE_*CACHE_MAINTENANCE

Emmanuel,

You haven't enabled those configs on armv8/ARM64 (and other arch's as well).
So if your patch is merged "as it is," I'm afraid that it will
break some functions/commands on such architectures that already
have cache maintenance operations without knowing those new configs.

Thanks,
