net: phy: fix up const issues in to_mdio_device() and to_phy_device()
Both to_mdio_device() and to_phy_device() "throw away" the const pointer
attribute passed to them and return a non-const pointer, which generally
is not a good thing overall. Fix this up by using container_of_const()
which was designed for this very problem.
