Derek Christ e89a9e22f5 ext,stdlib: Update integration of DRAMSys
The latest version of DRAMSys required several API changes which were
applied in this commit.

Also, the README for the usage of DRAMSys has been updated.

The updated version fixes a bug in DRAMSys that caused some full-system
simulations to loop endlessly.
