These are the same fixups as the riotboard's, itself propably taken from Linux, where mach-imx registers the same fixups for ar803x PHYs.
Some of these fixups can now be solved by PHY properties added since. Make use of them and make the remaining MMD indirect phy usage more compact by using phy_read_mmd_indirect.
