[Intel-wired-lan] [PATCH net-next v1 07/21] octeontx2: Move devlink registration to be last devlink command

[Leon Romanovsky <leon@kernel.org>]

From: Leon Romanovsky <leonro@nvidia.com>

This change prevents from users to access device before devlink is fully
configured. This change allows us to delete call to devlink_params_publish()
and impossible check during unregister flow.
