While building kernel Image for arm architecture on stable-rc 4.4 branch
the following build error found.

of_mdio: add helper to deregister fixed-link PHYs
commit 3f65047c853a2a5abcd8ac1984af3452b5df4ada upstream.

Add helper to deregister fixed-link PHYs registered using
of_phy_register_fixed_link().

Convert the two drivers that care to deregister their fixed-link PHYs to
use the new helper, but note that most drivers currently fail to do so.
