When rfkill is enabled, ath9k_hw unnecessarily configured the baseband to
turn off based on GPIO input, however that code was hardcoded to GPIO 0
instead of ah->rfkill_gpio.
Since ath9k uses software rfkill anyway, this code is completely unnecessary
and should be removed in case anything else ever uses GPIO 0.
