Subject: [PATCH] mx6ul(l)evk: Enable DM_ETH_PHY

> This fixes eth0 not initializing properly. Both eth0 and eth1 use the

> Net:
> Warning: ethernet at 20b4000 using MAC address from ROM
> eth1: ethernet at 20b4000 [PRIME]Could not get PHY for FEC0: addr 2
> After this patch they now look like
> Net:
> Warning: ethernet at 20b4000 using MAC address from ROM
> eth1: ethernet at 20b4000 [PRIME]Get shared mii bus on ethernet at 2188000
> Warning: ethernet at 2188000 using MAC address from ROM
> , eth0: ethernet at 2188000
> As an alternative to DM_ETH_PHY, FEC_MXC_SHARE_MDIO could also have been
> used to achieve the same effect.
