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