net: bcmgenet: Track per TX/RX rings statistics
__bcmgenet_tx_reclaim() is currently summing TX bytes/packets in a way
that is not SMP friendly, mutliples CPUs could run
__bcmgenet_tx_reclaim() independently and still update stats->tx_bytes
and stats->tx_packets, cloberring the other CPUs statistics.
Fix this by tracking per RX and TX rings the number of bytes, packets,
dropped and errors statistics, and provide a bcmgenet_get_stats()
function which aggregates everything and returns a consistent output.
