The fence instruction is used to enforce device I/O and memory ordering constraints in RISC-V. It can not be relied on to directly affect the data cache on every CPU. Andes' AX25 does not have a coherence agent. Its fence instruction flushes the data cache and is used to keep data in the system coherent. The implementation of flush_dcache_all in lib/cache.c is therefore specific to the AX25. Move it into the AX25-specific cache.c in cpu/ax25/. This also adds a missing new line between flush_dcache_all and flush_dcache_range in lib/cache.c.
