octeontx2-af: Install TC filter rules in hardware based on priority

As of today, hardware does not support installing tc filter
rules based on priority. This patch adds support to install
the hardware rules based on priority. The final hardware rules
will not be dependent on rule installation order, it will be strictly
priority based, same as software.

net: devlink: clean-up empty devlink_ops::info_get()

devlink_ops::info_get() is now optional and devlink will continue to
report information even if that callback gets removed.

Remove all the empty devlink_ops::info_get() callbacks from the
drivers.

net: devlink: let the core report the driver name instead of the drivers

The driver name is available in device_driver::name. 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.

Now that the core sets the driver name attribute, drivers are not
supposed to call devlink_info_driver_name_put() anymore. Remove
devlink_info_driver_name_put() and clean-up all the drivers using this
function in their callback.

octeontx2: Move devlink registration to be last devlink command

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.

devlink: Make devlink_register to be void

devlink_register() can't fail and always returns success, but all drivers
are obligated to check returned status anyway. This adds a lot of boilerplate
code to handle impossible flow.

Make devlink_register() void and simplify the drivers that use that
API call.
