    ramips: remove factory image for TP-Link Archer C2 v1
    
    Initial commit 8375623a0640 ("ramips: add support for TP-Link Archer
    C2") contains detailed installation instructions, which do not mention
    a factory image. From what I can see, no support to install OpenWrt
    through the vendor web interface has been added since. The factory
    image is also conspicuously absent from the device page in the wiki.
    Yet, it is available for download.
    
    I bricked my Archer C2 loading the factory image through the web UI.
    Serial showed this error during bootloop:
    
      Uncompressing Kernel Image ... LZMA ERROR 1 - must RESET board to recover
    
    This patch disables the undocumented factory image so users won't get
    tricked into thinking easy web UI flashing actually works.
