mem-ruby: Support atomic_noncaching acceses in ruby
Ruby has no support for atomic_noncaching accesses, which prevents using it with kvm-cpu. This patch fixes this by directly forwarding atomic requests from the ruby port/sequencer to the corresponding directory based on the destination address of the packet.
