[PATCH u-boot-marvell 5/9] arm: mvebu: turris_mox: Remove hardcoded ethernet node names

[Pali Rohár]

Armada 3720 DTS files in upstream kernel use ethernet nodes named
'ethernet at 30000' and 'ethernet at 40000'. U-Boot have them named 'neta at 30000'
and 'neta at 40000'. To have Turris Mox U-Boot board code independent of
ethernet node names, find ethernet node via alias.
