On AT91 SoCs, the User Register (USRIO) exposes a switch to configure the "Reduced" or "Traditional" version of the Media Independent Interface (RMII vs. MII or RGMII vs. GMII). As on the older EMAC version, on GMAC, this switch is set by default to the non-reduced type of interface, so use the existing capability and extend it to GMII as well. We then keep the current logic in the macb_init() function. The capabilities of sama5d2, sama5d4 and sama5d3 GEM interface are updated in the macb_config structure to be able to properly enable them with a traditional interface (GMII or MII).
