Subject: ARM: Include IDE/CF controller by default in PBX model.

Frame buffer and boot linux:
./build/ARM_FS/m5.opt configs/example/fs.py --benchmark=ArmLinuxFrameBuf --kernel=vmlinux.touchkit
Linux from a CF card:
./build/ARM_FS/m5.opt configs/example/fs.py --benchmark=ArmLinuxCflash --kernel=vmlinux.touchkit
Run Android
./build/ARM_FS/m5.opt configs/example/fs.py --benchmark=ArmAndroid --kernel=vmlinux.android
Run MP
./build/ARM_FS/m5.opt configs/example/fs.py --benchmark=ArmLinuxCflash --kernel=vmlinux.mp-2.6.38
