[PATCH] arm: mvebu: turris_omnia: Set ETHPRIME to DT alias

[Pali Rohár]

CONFIG_ETHPRIME can be set to DT node name or alias which refers to DT
node. Define ethernet aliases and set ETHPRIME to eth2 which refers to WAN
ethernet port. This removes hardcoded DT node name from U-Boot
configuration file.
