So not much reactions here .. a bit more on IRC, where Olof suggested
that rather than a file containing a path, we could use a symlink since
the devtree is now in sysfs, so we can do relative links.

That means keeping the legacy "devspec" files in the few places where
they exist, possibly behind a deprecated-default-y config option (though
we might never be able to deprecate them...), but there aren't many.

Any preference either way ?

Cheers,
Ben.
