Log:
  [atheros] [mips] Add the GPIO driver (back) to the TL-WDR3600/TL-WDR4300 kernel.
  
  So it turns out that sometime in the past I removed the GPIO bits here
  and was going to move it into a module in order to save a little space.
  However, it turns out that was a mistake on this particular AP - it
  uses a pair of GPIO lines to control the two receive LNAs on the 2GHz
  radio and without them enabled the radio is a LOT DEAF.
  
  With this re-introduced (and some replacement userland tools to save
  space, *cough* cpio/libarchive) I can actually use these chipsets
  again as a 2G station.  Without the LNA the AP was seeing a per-radio
  RSSI upstairs here of around 3-5dB, with the LNA on it's around 15dB,
  more than enough to actually use wifi upstairs and also in line with
  the other Atheros / Intel devices I have up here.
  
  Big oopsie to Adrian.  Big, big oopsie.
