Subject: [PATCH] ramips: fix Archer C20i wireless MAC address

The TP-Link Archer C20i previously had a generic Ralink MAC address set
for both radios, as the caldata does only contain a generic MAC address.

Set the MAC address from the vendor firmware for both radios to assign
unique MAC addresses to every device.
