net: hns3: create new rss common structure hclge_comm_rss_cfg

mainline inclusion
from mainline-master
commit 9667b814
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I4Q02P
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=9667b814387c

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

Currently PF stores its rss parameters in vport structure. VF stores rss
configurations in hclgevf_rss_cfg structure. Actually hns3 rss parameters
are same beween PF and VF. The two set of rss parameters are redundent and
may add extra bugfix work.

So this patch creates new common rss parameter struct(hclge_comm_rss_cfg)
to unify PF and VF rss configurations.

These new structures will be used to unify rss configurations in PF and VF
rss APIs in next patches.
