ethtool: add compat for devlink info
If driver did not fill the fw_version field, try to call into
the new devlink get_info op and collect the versions that way.
We assume ethtool was always reporting running versions.
v4:
- use IS_REACHABLE() to avoid problems with DEVLINK=m (kbuildbot).
v3 (Jiri):
- do a dump and then parse it instead of special handling;
- concatenate all versions (well, all that fit :)).
