mem-ruby: Prevent ruby from crashing on CMOs

Ruby has no support for cache maintenace operations. As a workaround,
after printing a warning, we treat them as no-ops in the memory system
and respond immediately without handling them. There should be
workarounds in the memory system already that allow execution to
proceed without the requirement for cache maintenance operations.
