net: devlink: turn devlink into a built-in
Being able to build devlink as a module causes growing pains. First all drivers had to add a meta dependency to make sure they are not built in when devlink is built as a module. Now we are struggling to invoke ethtool compat code reliably. Make devlink code built-in, users can still not build it at all but the dynamically loadable module option is removed.
