net: hns3: refactor dump qos buf cfg of debugfs
Currently, user gets qos buffer config by implementing debugfs command
"echo dump qos buf cfg > cmd", this command will dump info in dmesg.
It's unnecessary and heavy.
To optimize it, create a single file "qos_buf_cfg" in tm directory
and use cat command to get info. It will return info to userspace,
rather than record in dmesg.
The display style is below:
$ cat qos_buf_cfg
tx_packet_buf_tc_0: 0x120
tx_packet_buf_tc_1: 0x120
tx_packet_buf_tc_2: 0x120
tx_packet_buf_tc_3: 0x120
tx_packet_buf_tc_4: 0x0
tx_packet_buf_tc_5: 0x0
tx_packet_buf_tc_6: 0x0
tx_packet_buf_tc_7: 0x0
