config: Add a DRAM efficiency-sweep script

This patch adds a configuration that simplifies evaluation of DRAM
controller configurations by automating a sweep of stride size and
bank parallelism. It works in a rather unconventional way, as it needs
to print the traffic generator stimuli based on the memory
organisation. Hence, it starts by configuring the memory, then it
prints a traffic-generator config file, and loads it.

The resulting stats have one period per data point, identified by the
stride size, and the number of banks being used.

All regressions pass
