nx: Disable the GMS SetupWraith pairing wizard

* Users can still send the key event for pairing  on the deivce
  to open BT pairing - resolves all the complaints about
  not being able to use USB keyboards, JoyCons over serial, etc
  because SetupWraith prevents moving past the pairing wizard
  screen without successfully pairing a remote.
