Made DRAMCtrl a ClockedObject, with DRAMInterface defined as an AbstractMemory. The address ranges are now defined per interface. Currently the model only includes a DRAMInterface but this can be expanded for other media types. The controller object includes a parameter to the interface, which is setup when gem5 is configured.
