net: dsa: allow reporting of standard ethtool stats for slave devices
Jakub pointed out that we have a new ethtool API for reporting device statistics in a standardized way, via .get_eth_{phy,mac,ctrl}_stats. Add a small amount of plumbing to allow DSA drivers to take advantage of this when exposing statistics.
