This fixes eth0 not initializing properly. Both eth0 and eth1 use the MDIO interface on eth1 to access their PHYs. However, without DM_ETH_PHY, eth0 still tries to use its own MDIO interface to access its phy. Before this patch, a boot log might contain lines like
Net: Warning: ethernet@20b4000 using MAC address from ROM eth1: ethernet@20b4000 [PRIME]Could not get PHY for FEC0: addr 2
After this patch they now look like
Net: Warning: ethernet@20b4000 using MAC address from ROM eth1: ethernet@20b4000 [PRIME]Get shared mii bus on ethernet@2188000
Warning: ethernet@2188000 using MAC address from ROM , eth0: ethernet@2188000
As an alternative to DM_ETH_PHY, FEC_MXC_SHARE_MDIO could also have been used to achieve the same effect.
