Currently, max scheduling rates configuration of pg, pri and port are set
to 100000Mbps, which is the maximum bandwidth of hns3 network engine with
revision_id equals 0x21. However, max scheduling rate configuration should
be set to hardware based on the actual hardware board environment.

The max_tm_rate in struct hns3_hw, meaning the rate, is obtained from
firmware. So we should use the variable to configure the max scheduling
rate.
