/* AMCC_TODO:
 * Find out of the choice for the emac for MDIO is from the bridges,
 * i.e. ZMII or RGMII as approporiate.  If the bridges are not used
 * to determine the emac for MDIO, then is the SDR0_ETH_CFG[MDIO_SEL]
 * used?  If so, then this routine below does not apply to the 460EX/GT.
 *
 * sr: Currently on 460EX only EMAC0 works with MDIO, so we always
 * return EMAC0 offset here
