====================
net: enetc: change some statistics to 64-bit

The port MAC counters of ENETC are 64-bit registers and the statistics
of ethtool are also u64 type, so add enetc_port_rd64() helper function
to read 64-bit statistics from these registers, and also change the
statistics of ring to unsigned long type to be consistent with the
statistics type in struct net_device_stats.
