====================
net: enetc: improve statistics for v1 and add statistics for v4

For ENETC v1, some standardized statistics were redundantly included in
the unstructured statistics, so remove these duplicated entries.
Previously, the unstructured statistics only contained eMAC data and
did not include pMAC data; add pMAC statistics to ensure completeness.

For ENETC v4, the driver previously reported MAC statistics only for the
internal ENETC (Pseudo MAC). Extend the implementation to provide
additional statistics for both the internal ENETC and the standalone
ENETC.
