Altera TSE: Move PHY get addr and MDIO create
Move PHY get addr and MDIO create to a new function to improve readability and make it easier to avoid its usage. This will be useful for example in the case where there is no PHY chip. Signed-off-by: Walter Lozano <walter@vanguardiasur.com.ar> Signed-off-by: David S. Miller <davem@davemloft.net>
