[PATCH v2 net-next 1/3] net: mscc: ocelot: remove redundant stats_layout pointers

From: Colin Foster
Date: Sat Nov 19 2022 - 18:14:46 EST

Ever since commit 4d1d157fb6a4 ("net: mscc: ocelot: share the common stat
definitions between all drivers") the stats_layout entry in ocelot and
felix drivers have become redundant. Remove the unnecessary code.

Suggested-by: Vladimir Oltean <olteanv@xxxxxxxxx>
Signed-off-by: Colin Foster <colin.foster@xxxxxxxxxxxxxxxx>

v1->v2
* Fix unused variable build warning in v1
