hns3 udma: init software tables of qp/uar and others 

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


CVE: NA

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

When driver insmoded, tables as qp/uar/jetty/jfs/jfr/jfc
and others should be created.

UAR(user-area-region) is an independent structure between
context. It contains doorbell address and direct wqe
address.
