macb: Fix mii_phy_read and mii_phy_write functions
Enabling CONFIG_CMD_MII in AVR32 boards was not possible due to compile errors. This patch fixes miiphy_read and miiphy_write functions and registers them properly. Signed-off-by: Semih Hazar <semih.hazar@indefia.com> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>
