OpenWrt Support for WX5600

[L4ky]

@Thomas5401

@saladin b10_0410 has been rolled out. If you leave your Odido T-56 connected overnight as you normally would, it will be upgraded, so be careful. It includes all security measures I mentioned earlier: the config backup can't be decrypted anymore, mtk_uartboot no longer works, the root password isn't visible via serial anymore and the supervisor password has changed and is stored in an encrypted file. The latter also goes for the T-54 and NR5307 so far, so they're clearly upping their game.

I just got 2 WX5600 from a NL User.
They have b13.. uboot has password.

What can we do now?
