Right now, drivers still have to report this piece of information themselves in their devlink_ops::info_get callback function. In order to factorize code, make devlink_nl_info_fill() add the driver name attribute. nla_put() does not check if an attribute already exists and unconditionally reserves new space [1]. To avoid attribute duplication, clean-up all the drivers which are currently reporting the driver name in their callback.

Now that the core provides this information, the callback became empty. For such drivers, just removing the callback would prevent the core from executing devlink_nl_info_fill() meaning that "devlink dev info" would not return anything. Make the callback function optional by executing devlink_nl_info_fill() even if devlink_ops::info_get() is NULL. Remove all the empty devlink_ops::info_get() functions from the drivers. N.B.: the drivers with devlink support which previously did not implement devlink_ops::info_get() will now also be able to report the driver name.
