[coreboot] Abandoning ~250 coreboot patches older than 18 months

[Martin Roth]

It's patch cleanup time again.  This cleanup was last done almost 2
years ago, so there are a lot of old patches that haven't been touched
in a while.
Next week I'm going to abandon all of the open patches that haven't
been touched in over 18 months.

The list of roughly 250 patches to be abandoned is here:
https://review.coreboot.org/q/status:open+before:2018-02-1+project:coreboot

If anyone wants to take over any of these patches, just mention it in
the patch and if the author doesn't respond in a day or two, feel free
to let them know that you've adopted the patch.

As always, if there's anything that is still useful and shouldn't be
abandoned, a comment in the patch is enough to keep it alive in
gerrit.
