    ath79: ag71xx-mdio: remove phy-mask property
    
    The phy-mask property is read by the ag71xx-mdio driver to set the
    mii_bus's phy_mask field. On OF platforms, the devicetree is expected to
    provide all present ethernet phy-s however, so the phy_mask field is
    later set to all-ones. Having a devicetree override is of no use then,
    so let's drop it.
