ruby: call setMRU from L1 controllers, not from sequencer
Currently the sequencer calls the function setMRU that updates the replacement policy structures with the first level caches. While functionally this is correct, the problem is that this requires calling findTagInSet() which is an expensive function. This patch removes the calls to setMRU from the sequencer. All controllers should now update the replacement policy on their own. The set and the way index for a given cache entry can be found within the AbstractCacheEntry structure. Use these indicies to update the replacement policy structures.
