    igc: remove unnecessary PHY ID checks
    
    I225 devices have only one PHY vendor. There is unnecessary to check
    _I_PHY_ID during the link establishment and auto-negotiation process,
    the checking also caused devices like i225-IT failed. This patch is to
    remove the mentioned unnecessary checking.
