There is a need to support modification of Tx scheduler tree, in the

Hierarchy QoS implemented entirely in the hardware.

This patch implemenents devlink-rate API. It also exports initial
default hierarchy. It's mostly dictated by the fact that the tree
can't be removed entirely, all we can do is enable the user to modify
it. For example root node shouldn't ever be removed, also nodes that
have children are off-limits.

Feel free to post a v12 with these fixed, I'll review the latest
tomorrow.
