ipq806x: Stabilize LAN 2 MAC address, interface ordering

Part 1 of openwrt#13629 split. * Sets the LAN 2 MAC address in the DTS by deriving it from LAN 1's address. The factory OS derives this from the `eth1addr` u-boot env variable, but the nvmem_u-boot-env driver doesn't support parsing MAC addresses from fields other than `ethaddr`. But for all of the device samples I've checked (~10) it derives the correct MAC. * Updates 02_network to ensure that interfaces are assigned to roles correctly and consistently.
