cpu: Allow creation of traffic gen from generic SimObjects
This patch allows to instantiate a Traffic generator starting from a
generic SimObject, so that linking to a BaseTrafficGen only is no longer
mandatory. This permits SimObjects different than a BaseTrafficGen to
instantiate generators and to manually specify the MasterID they
will be using when generating memory requests.
