hns3 udma: support config congestion control algorithms

driver inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I85R2F


CVE: NA

---------------------------------------------------------------------

This patch supports config congestion control algorithms which as known as
SCC. UDMA driver supports four scc algorithms: DCQCN, LDCP, HC3, and DIP,
and each algorithm corresponds to a different QP context configuration in
six fields. Only DIP need to config dip_idx.
