layerscape: clean up kernel patches

A previous patch disaggregated kernel patch 601 intending to
reverse the ndo_get_stats64 change, but it also dropped
many other changes without a reason. This caused build issue
for layerscape. This patch is to fix that with below steps.
1. Reversed patch "1c4415a layerscape: reverse changes to ndo_get_stats64",
   but kept kernel patch 701 which was a proper fix.
2. Reversed the ndo_get_stats64 change in kernel patch 601.
3. Renamed patch 601 (net patch) to 202 (core-linux patch). Maybe it's
   more proper.

Fixes: 1c4415a679f9 ("layerscape: reverse changes to ndo_get_stats64")
