Subject: octeontx2: Move devlink registration to be last devlink command
Patch-mainline: v5.16-rc1
Git-commit: 1d264db405cb02c7a225be8e244d171156f6e668
References: jsc#SLE-24682

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.
