Subject: [PATCH 29/30] net/hns3: support power monitor

[ upstream commit 9e1e7dded323ce424aebf992f6ddfa9656655631 ]

This commit supports power monitor on the Rx queue descriptor of the
next poll.

Note: Although rte_power_monitor() on the ARM platform does not support
callback, this commit still implements the callback so that it does not
need to be adjusted after the ARM platform supports callback.
