ath9k: unset the default LED pin if used by platform buttons
Unset the default LED gpio pin if the same gpio pin is used by a button defined via platform button. It prevents the change of the GPIO value on wireless up/down or wireless traffic. Fixes: FS#1129 Signed-off-by: Mathias Kresin <dev@kresin.me>
