net: hns3: Add "tc config" info query function

This patch prints tc config information.

debugfs command:
echo dump tc > cmd

Sample Output:
root@(none)# echo dump tc > cmd
hns3 0000:7d:00.0: weight_offset: 14
hns3 0000:7d:00.0: tc(0): no sp mode
hns3 0000:7d:00.0: tc(1): no sp mode
hns3 0000:7d:00.0: tc(2): no sp mode
hns3 0000:7d:00.0: tc(3): no sp mode
hns3 0000:7d:00.0: tc(4): no sp mode
hns3 0000:7d:00.0: tc(5): no sp mode
hns3 0000:7d:00.0: tc(6): no sp mode
hns3 0000:7d:00.0: tc(7): no sp mode
