From: Jian Shen <shenjian15@huawei.com>
Arnd reported that there are two build warning for on-stasck
buffer oversize. As Arnd's suggestion, using seq file way
to avoid the stack buffer or kmalloc buffer allocating.

From: Jian Shen <shenjian15@huawei.com>
Use seq_file for files in debugfs. This is the first
modification for reading in hclge_debugfs.c.
This patch use seq_file for the following nodes:
tm_nodes/tm_priority/tm_qset/tm_map/tm_pg/tm_port/tc_sch_info/
qos_pause_cfg/qos_pri_map/qos_dscp_map/qos_buf_cfg
