mem: Make MemCtrl a ClockedObject

Browse Source 
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.
