net: enetc: expose some standardized ethtool counters 



Structure the code in such a way that it can be reused later for the
pMAC statistics, by just changing the "mac" argument to 1.

Usage:
ethtool --include-statistics --show-pause eno2
ethtool -S eno0 --groups eth-mac
ethtool -S eno0 --groups eth-ctrl
ethtool -S eno0 --groups rmon
