Add the optional "rockchip,sgmii-mac-sel" property to allow the device tree to select which GMAC controller is used for SGMII. The property takes a value of 0 (GMAC0) or 1 (GMAC1). The hardware reset value is 1 (GMAC1), but this can be overridden by setting the property to 0 for boards where SGMII is connected to GMAC0. This is necessary for boards such as the Ariaboard Photonicat, where the SGMII interface is connected to GMAC0 and needs to be explicitly configured.
