Get basic full-system working with AtomicSimpleCPU.

SConscript:
    Comment out sinic for now... needs to be fixed to compile under newmem.
configs/test/SysPaths.py:
    Fix paths.
configs/test/fs.py:
    SimpleCPU -> AtomicSimpleCPU
    Fix vmlinux path
cpu/simple/atomic.cc:
    Fix suspendContext() so quiesce works.
    Don't forget to checkForInterrupts().
cpu/simple/base.cc:
    Minor fix to interrupt check code.
dev/ide_disk.hh:
    Don't declare regStats() in header since it's not in
    .cc file anymore (will need to add it back in when
    stats are added back).
dev/io_device.cc:
    Set packet dest to Packet::Broadcast.
dev/pciconfigall.cc:
    Set PCI config packet result to Success.
python/m5/objects/Root.py:
    Add debug object to Root so things like break_cycles
    can be set from command line.
