ath9k: uses/needs led_classdev_[un]register

From: Randy Dunlap <[email protected]>

ath9k uses LED classdev functions, so it needs to either select or depend on them. This patch uses the same selects that ath5k uses...

drivers/built-in.o: In function `ath_unregister_led':
main.c:(.text+0x138c1d): undefined reference to led_classdev_unregister' drivers/built-in.o: In function ath_register_led':
main.c:(.text+0x139c16): undefined reference to `led_classdev_register' make[1]: *** [.tmp_vmlinux1] Error 1
