Update cpus to use the getPort function to use a connector object to connect the I/D cache ports to memory

configs/test/test.py:
    Update to use new cpu getPort functionality
src/cpu/base.cc:
    Make cpu's a memObject to expose getPort interface
src/cpu/base.hh:
    Make cpu's a memObject to export getPort interface
src/cpu/simple/atomic.cc:
src/cpu/simple/atomic.hh:
src/cpu/simple/timing.cc:
src/cpu/simple/timing.hh:
    Now use the connector via getPort interface
src/mem/cache/base_cache.cc:
    Make sure the cache recognizes all port names
