net: hns3: Add "FD flow table" info query function



All the Flow Director rules are stored in tcam blocks.
For each bit of tcam entry, the match value
depends on two input value(x, y).

debugfs command:
echo dump fd tcam > cmd

Sample output:
root@(none)# echo dump fd tcam > cmd
hns3 0000:7d:00.0: read result tcam key x(31):
