    sandybridge: Make inclusion of me.bin optional
    Current build configuration always wants to include an Intel Management
    Engine firmware (me.bin) on Sandy Bridge systems. However, we can have
    a working coreboot without it, as long as the factory delivered ME
    firmware is kept untouched in the flash ROM. So let the user decide if
    a ME firmware will be included in the build.
