I'd prefer not to do it mechanically, please check the things that
changed to see if they made sense.

Two boards select this, and are apparently enabled by default.
Why? Could we remove the 'select' and leave this line?

This was removed in v3.11, but a lot of defconfigs still
try to enable it. Maybe do them all at once?

Same thing, removed in v4.6, but still referenced in 199 files.
