RDMA/hns: Support setting GSI QP SL via debugfs
Due to the hardware contraint, CQEs may be dropped when a UD QP
sends with multiple SLs. For GSI QP, provide debugfs to allow users
to set a fixed SL. This is only allowed when the device is link down.
Example:
# cat /sys/kernel/debug/hns_roce/<PCI>/gsi_sl
0
# echo 3 > /sys/kernel/debug/hns_roce/<PCI>/gsi_sl
# cat /sys/kernel/debug/hns_roce/<PCI>/gsi_sl
3
