nvethernetrm: add HW and SW counters' support

Browse Source 
These stats are read from MAC HW RMON counters as well as from Core
and DMA path.

ethtool -S <interface> is used to get statistics.

There are 3 stats captured currently
1) ether_mmc_counters: EQOS HW RMON counters
2) ether_xtra_stat_counters: SW counters from osi/core
3) ether_xtra_dma_stat_counters: SW counters from osi/dma
