Ports now have a pointer to the MemObject that owns it (can be NULL).

src/cpu/simple/atomic.hh:
    Port now takes in the MemObject that owns it.
src/cpu/simple/timing.hh:
    Port now takes in MemObject that owns it.
src/dev/io_device.cc:
src/mem/bus.hh:
    Ports now take in the MemObject that owns it.
src/mem/cache/base_cache.cc:
    Ports now take in the MemObject that own it.
src/mem/port.hh:
src/mem/tport.hh:
    Ports now optionally take in the MemObject that owns it.
