API Change for phy_dev

[mickflemm]

On recent kernel versions:
phydev->advertising = phydev->supported
will not work since they are not u32 anymore but bitfields, you should instead use linkmode_* functions to manipulate them, e.g.:

linkmode_and(phydev->advertising, phydev->advertising, phydev->supported);
linkmode_copy(priv->phy_dev->advertising, priv->phy_dev->supported);
