mtest tests many types of memory accesses in many different conditions. If
dcache is enabled, memory accesses are likely bursts, and some memory accesses
are simply skipped. Hence, mtest results may change depending on dcache state.
This patch prints the dcache state at the beginning of mtest so as to keep the
user informed of the test conditions.
