net: hns3: refactor dump reg dcb info of debugfs
Currently, the debugfs command for reg dcb info is implemented by
"echo xxxx > cmd", and record the information in dmesg. It's
unnecessary and heavy. To improve it, create a single file
"dcb" for it, and query it by command "cat dcb",
return the result to userspace, rather than record in dmesg.
The display style is below:
$ cat dcb
