net: fec_mxc: Fix setting of RCR for xMII
At least on i.MX25, the RMII mode did not work, which is fixed by this patch. The MII_MODE bit of the FEC RCR register means xMII, i.e. 'not 7-wire', so set it accordingly. According to the xMII and 7-wire (aka GPSI) standards, full duplex should be available on xMII, but not on 7-wire, so set FCE accordingly. The FEC may support full duplex for 7-wire too, but the reference manual does not say that, so avoid an invalid assumption. Actually, the choice between half and full duplex also depends on the endpoint/switch/repeater configuration, so a config option could be added for that, but there has been no need for it so far.
