Ali Saidi f6fc18f03d fullsys now builds and runs for about one cycle
SConscript:
    easier to fix than temporarily remove
cpu/simple/cpu.cc:
cpu/simple/cpu.hh:
    mem needed for both fullsys and syscall
dev/baddev.cc:
    fix for new mem system
dev/io_device.cc:
    fix typo
dev/io_device.hh:
    PioDevice needs to be a memobject
dev/isa_fake.cc:
dev/pciconfigall.cc:
dev/pciconfigall.hh:
    fix for new mem systems
dev/platform.cc:
dev/platform.hh:
dev/tsunami.cc:
dev/tsunami.hh:
    rather than the platform have a pointer to pciconfig, go the other
    way so all devices are the same and can have a platform pointer
