ath79: ag71xx: Explicitly register mdio bus after ag71xx_hw_init() for ar7240
mdio bus isn't a standalone device on ar7240. (and maybe older SoCs?) Use simple-mfd for ar7241 and later SoCs to get mdio1 ready before gmac0 For ar7240 and older chips, manually create platform device after ag71xx_hw_init() in ag71xx_probe()to get mdio0 ready between ag71xx_hw_init() and ag71xx_phy_connect().
