Subject: [PATCH] phylib: SIOCGMIIREG/SIOCSMIIREG: allow access to all mdio addresses

phylib would silently ignore the phy_id argument to these ioctls and
perform the read/write with the active phydev address, whereas most
non-phylib drivers seem to allow access to all mdio addresses
(E.G. pcnet_cs).
