net: cadence: macb: Report standard stats

Browse Source 
Report standard statistics using the dedicated callbacks instead of
get_ethtool_stats.

OCTTX is split over two registers. Accumulating these registers
separately in gem_stats just means we need to combine them again later.
Instead, combine these stats before saving them, like is done for
ethtool_stats.
