Add per-port RMON statistics support for the MxL862xx DSA driver,
covering hardware-specific ethtool -S counters, standard IEEE 802.3
MAC/ctrl/pause statistics, and rtnl_link_stats64 via polled 64-bit
accumulation.

Changes since v1:
 * trim mxl862xx_mib[] to counters not covered elsewhere only
 * remove histogram counters (moved to .get_rmon_stats)
 * remove RMON error counters (moved to .get_rmon_stats)
 * remove counters already in .get_eth_mac_stats
 * remove counters already in .get_stats64
 * add mxl862xx_rmon_ranges[] and mxl862xx_get_rmon_stats()
