    mediatek: disable unsupported background radar detection
    
    MT7915 requires an additional antenna for background radar scanning.
    Disable this feature in the following devices that do not have a
    separate DFS antenna:
      linksys,e8450
      ruijie,rg-ew3200gx-pro
      xiaomi,redmi-router-ax6s
