    kirkwood: Add missing phy-mode and fixed links
    
    Copied from original Andrew's Lunn commit message:
    
        The DSA framework has got more picky about always having a phy-mode
        for the CPU port. The Kirkwood Ethernet is an RGMII port. Set the
        switch to impose the RGMII delays.
    
        Additionally, the cpu label has never actually been used in the
        binding, so remove it.
    
    This commit backport change from upstream and fix downstream EA3500 dts.
