45363ea658 Have bus use the BadAddress device to handle bad addresses. The O3 CPU should be able to boot into Linux with caches on after this change.
src/mem/bus.cc:
src/mem/bus.hh:
    Bus now will be setup with a default responder, unless the user overrides it.  This default responder should return BadAddress if no matching port is found.
src/python/m5/objects/Bus.py:
    Bus now has a default responder for FS mode if the user doesn't override it.  It returns BadAddress if no matching port is found.
src/python/m5/objects/Tsunami.py:
    Add bad address device.  Also record when the user has specified their own default responder.

src/mem/cache/base_cache.cc:
    Have caches return a new functional port whenever asked for them.  I'm pretty sure this is desired behavior.  Ron can correct me if it's not.

7665be4f70 make it so that you can do a standard switch without the caches option. this will have only the o3 cpu have a cache, rather than timing (warmup) + o3 have cache.
