Nikolay Martynov 4705398bbf ramips: rename interfaces for tplink er605v2
Currently eth1 (which is the first "lan" interface) doesn't work on this device.
During boot the following can be seen in logs:

```

[    6.919904] mtk_soc_eth 1e100000.ethernet wan: renamed from eth1
```

So the problem seems to be the fact that built-in gmacs get default
names (eth0/eth1) and are renamed after switch ports are initialized. This means
that when switch port with name `eth1` is brought up this name is still used by
gmac1 causing switch port's init to fail.

This patch just renames the ports to avoid name collision.
Note: this will break existing configs for this device because it renames all
the ports. This should not be major problem because this device doesn't have a
proper OEM image and is only flashable with serial access, meaning there should
not be many users.
