[PATCH net-next 3/9] phy: fixed_phy: Set supported speed in phydev

[Andrew Lunn <andrew@lunn.ch>]

Set the supported field of the phydev to indicate the speed features
of the phy. If the phy is never attached to a netdev, but used in an
adjust_link() function, the speed will be incorrectly evaluated to
10/half rather than the correct speed/duplex.
