ice driver needs an ability to create devlink-rate nodes from inside the
driver. We have default Tx-scheduler tree that we would like to
export as devlink-rate objects.

There is also a need to support additional parameters, besides two that
are supported currently:
tx_priority - priority among siblings (0-7)
tx_weight - weights for the WFQ algorithm (1-200)

Allow creation of nodes from the driver, and introduce new argument
to devl_rate_leaf_create, so the parent can be set during the creation
of the leaf node.

Implement new parameters - tx_priority, tx_weight.

Allow modification of the priv field in the devlink_rate from parent_set
callbacks. This is needed because creating nodes without parents doesn't
make any sense in ice driver case. It's much more elegant to actually
create a node when the parent is assigned.

This should be split into like 3-4 patches.
