This patch syncs the DRAMPower library of gem5 to the external github (https://github.com/ravenrd/DRAMPower). The version pulled in is the commit: 90d6290f802c29b3de9e10233ceee22290907ce6 from 30th Oct. 2016. This change also modifies the DRAM Ctrl interaction with the DRAMPower, due to changes in the lib API in the above version. Previously multiple functions were called to prepare the power lib before calling the function that would calculate the enery. With the new API, these functions are encompassed inside the function to calculate the energy and therefore should now be removed from the DRAM controller. The other key difference is the introduction of a new function called calcWindowEnergy which can be useful for any system that wants to do measurements over intervals. For gem5 DRAM ctrl that means we now need to accumulate the window energy measurements into the total stat.
