It is very common boot Chromebooks from an USB device, the EC needs to be
built-in in order to boot from these devices, otherwise you should use an
initramfs. I'd like to avoid forcing people to build an initramfs just to boot
from these devices if possible, in fact, my usual workflow is without initramfs,
and knowing that with the default defconfig just should boot helps a lot sometimes.

Note that, it's not the case for EC subdevices, these are already build as modules.

BTW, Lee asked if this patch should be squashed with the patches that really
renames the config options to help bisect ability, I don't have a hard opinion
as I don't usually run the config option between bisection steps, so please let
me know what do you prefer and I'll respin the patches ASAP if that's the case.

Thanks,
Enric
