[PATCH] ramips: remove factory image for TP-Link Archer C20 v1

[Stijn Segers]

Similarly to the Archer C2 v1, the Archer C20 v1 will brick when one
tries to flash an OpenWrt factory image through the TP-Link web UI.
The wiki page contains an explicit warning about this [1].

Disable the factory image altogether since it serves no purpose.
