ar71xx: vanity changes for dir-825-c1

This patch

- changes the color names from orange to amber
- changes the name of GPIO 13 from WIFI_BGN (wifi_bgn) to WLAN_2G
  (wlan2g) to be more consistent with the other routers' files
- changes the descriptions of the hardware keys to be a tad more
  explicit
