da850/omap-l138: Enable auto negotiation in RMII mode

Browse source 
On DA850/OMAP-L138 it was observed that in RMII mode,
auto negotiation was not performed. This patch enables
auto negotiation in RMII mode. Without this patch, EMAC
initialization takes more time and sometimes tftp fails
in RMII mode.
