microblaze: cache: introduce flush_cache_all()
All flush_cache() calls in microblaze code are supposed to flush the
entire instruction and data caches, so introduce flush_cache_all()
helper to handle this.
Also, provide implementations for flush_dcache_all() and
invalidate_icache_all() so that icache and dcache u-boot commands can
work.
