config: Use shared cache config for regressions
This patch uses the common L1, L2 and IOCache configuration for the regressions that all share the same cache parameters. There are a few regressions that use a slightly different configuration (memtest, o3-timing=mp, simple-atomic-mp and simple-timing-mp), and the latter are not changed in this patch. They will be updated in a future patch. The common cache configurations are changed to match the ones used in the regressions, and are slightly changed with respect to what they were. Hopefully this means we can converge on a common base configuration, used both in the normal user configurations and regressions. As only regressions that shared the same cache configuration are updated, no regressions are affected.
