Subject: [PATCH 11/18] lenovo/x230: set me_state=Disabled in cmos.default

I only recently found out about this. It's possible to use me_cleaner to
do the same thing, but some people might just flash coreboot and not do
anything with the ME region

With this change, the ME is set to disabled. It's my understanding that this
will accomplish more or less the same thing as me_cleaner, without actually
using that. Of course, I still recommend using me_cleaner

I saw this when I audited coreboot's git history, and saw this:
