It should be up to an architecture to decide how to implement cache functions, and if they need to use weak functions or not. Allowing the cache command to be built without cache functionality implemented is unhelpful. Further, guard the call to noncached_set_region with CONFIG_SYS_NONCACHED_MEMORY as that's when it's implemented and again is an architecture specific detail.
