concerning this, we had added some work to pass from the platform

http://git.stlinux.com/?p=stm/linux-stm.git;a=blob;f=drivers/net/ethernet/stmicro/stmmac/stmmac_platform.c;h=2d540e1d2151e4412a5af5356d24d5c6b66cf72e;hb=HEAD

I wanted to also do a clean-up and update the DT support because
the binding documentation remains obsolete etc.
