powerpc/cache: add cache flush operation for various e500
Various e500 core have different cache architecture, so they need different cache flush operations. Therefore, add a callback function cpu_flush_caches to the struct cpu_spec. The cache flush operation for the specific kind of e500 is selected at init time. The callback function will flush all caches in the current cpu.
