====================
net: stmmac: fix regression on SPEAr3xx SOC

The ethernet driver used on old SPEAr3xx soc was previously supported on old
kernel. Some regressions were introduced during the different updates leading
to a broken driver for this soc.

This series fixes these regressions and brings back ethernet on SPEAr3xx.
Tested on a SPEAr320 board.
