Sync DRAMPower to external tool This patch syncs the DRAMPower library of gem5 to the external one on github (https://github.com/ravenrd/DRAMPower) of which I am a maintainer. The version used is the commit: 902a00a1797c48a9df97ec88868f20e847680ae6 from 07. May. 2016. Committed by Jason Lowe-Power <jason@lowepower.com>
