    This patch adds the following property for arc_emac.
    
    1) phy-reset-gpios:
    The phy-reset-gpio is an optional property for arc emac device tree boot.
    Change the binding document to match the driver code.
    
    2) phy-reset-duration:
    Different boards may require different phy reset duration. Add property
    phy-reset-duration for device tree probe, so that the boards that need
    a longer reset duration can specify it in their device tree.
    
    Anyway, we can add the above property for arc emac.
