nfp: don't report standard netdev statistics in ethtool 

We have been recently called out as a bad example for reporting
standard netdev statistics as part of ethtool.  Fix that :)

Removing standard statistics allows us to simplify the structure
holding definitions since we no longer have to mux different types
of statistics.
