ath79: fix MAC addresses for ethernet on ZyXEL NBG6716
MAC addresses of the ethernet devices (eth0 & eth1) are randomly set at
boot time by the ag71xx driver, because it is currently not possible to
retrieve MAC addresses in ASCII format within the DTS file.
This commit works around this behaviour by setting the MAC addresses
during the preinit phase.
The same has been implemented recently for the Siemens WS-AP3610 in
d2b8ccb1c04d ("ath79: add support for Siemens WS-AP3610").
MAC assignment in vendor firmware is as follows:
use vendor address OpenWrt
2g wifi0 ethaddr -> wlan1
5g wifi1 ethaddr +1 -> wlan0
lan eth1 ethaddr +2 -> eth0
wan eth0 ethaddr +3 -> eth1
ethaddr is retrieved by $(mtd_get_mac_ascii u-boot-env ethaddr)
Note that both Wifi and ethernet indexing is swapped in OpenWrt
compared to vendor firmware.
