net: macb: enable GMAC IP without GE feature support
The User Register in GMAC IP is used to select interface type. When with GE feature, it is used to select interface between RGMII and GMII. If without GE feature, it is used to select interface between MII and RMII. Signed-off-by: Bo Shen <voice.shen@atmel.com> Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com>
