MEM: Prepare mport for master/slave split

This patch simplifies the mport in preparation for a split into a
master and slave role for the message ports. In particular,
sendMessageAtomic was only used in a single location and similarly so
sendMessageTiming. The affected interrupt device is updated
accordingly.
