[coreboot] [PATCH] Move CAR settings to board config for socket940 boards.

Since it's relatively easy to check, I think it's worthwhile to make sure
that no .config settings are changed when cleaning up settings.

1. ./util/abuild/abuild -C -a
2. grep CACHE coreboot-builds/*/config.h > before.txt
3. Apply your patch
4. grep CACHE coreboot-builds/*/config.h > after.txt
5. diff before.txt after.txt

abuild -C is "configure-only mode", and runs relatively quickly.

Thanks,
Myles
