ramips: fix Tenbay T-MB5EU v1 Wireless MAC

It was reported, that Tenbay T-MB5EU v1 do have incorrect Wireless MAC
address set on 2.4 and 5 GHz.

Some boards do not seem to have the correct MAC address set for the
external PHY of the MT7915 radio at caldata offset 0xa.

As the external PHY does not expose a DT binding (yet), fix up the mac
address in userspace.
