ath9k: fix unloading the module
Registering a GPIO chip with the ath9k device as parent prevents unload, because the gpiochip core increases the module use count. Unfortunately, the only way to avoid this at the moment seems to be to register the GPIO chip without a parent device Signed-off-by: Felix Fietkau <nbd@nbd.name>
