Subject: ath9k: Add a module parameter to invert LED polarity.

From: Vittorio Gambaletta (VittGam) <linux-wireless@vittgam.net>

commit cd84042ce9040ad038e958bc67a46fcfc015c736 upstream.

The LED can be active high instead of active low on some hardware.

Add the led_active_high module parameter. It defaults to -1 to obey
platform data as before.

Setting the parameter to 1 or 0 will force the LED respectively
active high or active low.
