Make sure we flush all data caches and their write buffers before flushing icache, otherwise random edge cases could crop up where stale data is read into icache from external memory. As fallout, punt the combined icache + dcache flush function since we cannot safely do them back to back -- the SSYNC is needed between the dcache flush and the icache flush.
