Add a little more tracing support for Bus/Port stuff.

src/base/traceflags.py:
    Sort flags so you can find things.
    Add BusAddrRanges flag for tracking RangeChange events
    separately from general bus activity.
src/mem/bus.cc:
    Add BusAddrRanges flag for tracking RangeChange events
    separately from general bus activity.
src/mem/port.cc:
src/mem/port.hh:
    Print Config trace message when peers are set up.
