ruby: Fixes clock domains in configuration files

This patch fixes scripts related to ruby by adding the ruby clock domain.
Now the L1 controllers and  the Sequencer shares the cpu clock domain,
while the rest of the components use the ruby clock domain.

Before this patch, running simulations with the cpu clock set at 2GHz or
1GHz will output the same time results and could distort power measurements.
