ext, mem: Pull DRAMPower SHA 90d6290 and rebase

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.

 ## 5. Usage
 
-src/cli/drampower.cc is the main interface file, which accepts user inputs to specify memory to be employed and the command or transaction trace to be analyzed. If the transaction trace (DRAM command scheduler) is being used, the users can specify the degree of bank interleaving required, the request size and the use of power-down or self-refresh options. Also, for DDR4 memories bank group interleaving can be specified. Dual-rank DRAMs are not yet supported by the command scheduler. Note: Speculative use of power-down or self-refresh modes will increase the trace length due to the power-up latencies of these power-saving modes.
