Add support for multiple ports on the memory. Hook up simple cpu to memory.

Ready to start testing if I could fix the linking errors I can't ever seem to fix.

cpu/simple/cpu.cc:
cpu/simple/cpu.hh:
    Add connecting of ports until builder can handle it.
mem/physical.cc:
    Add function to allocate a port in the object

    Remove some full_sys stuff untill needed
mem/physical.hh:
    Add function to allocate a port in the object
python/m5/objects/BaseCPU.py:
    Update the params
sim/process.cc:
    Make sure to use the right name (hopefully CPU constructor already called)
