net: hns: add support of pause frame ctrl for HNS V2
The patch adds support of pause ctrl for HNS V2, and this feature is lost
by HNS V1:
1) service ports can disable rx pause frame,
2) debug ports can open tx/rx pause frame.
And this patch updates the REGs about the pause ctrl when updated
status function called by upper layer routine.
