    ramips: mt7621: mikrotik 760igs (hEX S) fix SFP
    
    This device uses an AR8031/AR8033 chip to convert SoC gmac1
    RGMII to 1000base-x or sgmii for the SFP fibre cage.
    The SFP cage requires phy-mode rgmii-rxid, and without it will not
    recieve any packets: ethtool -S sfp rx_fcs_errors will increase when
    packets should be being received, but no other _rx counters will change.
    
    Fixes: c77858aa792 ("ramips: mt7621-dts: change phy-mode of gmac1 to rgmii")
