ipq40xx: use correct wired MAC-addresses for RUTX50

Browse Source 
The Teltonika RUTX50 mac-addresses on its wired interfaces are currently
random on every boot.

Setting the mac-addresses from device-tree using nvmem does not work, as
the vendor bootloader mangles the mtd partitions, removing the
nvmem-cells property.

To remedy the random mac-addresse, set the correct ones in preinit.
