Without this patch, an extra entry appears for AR9287 GPIO
that duplicates WLAN LED but in fact drives nothing:
gpiochip1: GPIOs 502-511, ath9k-phy0:
gpio-502 ( |netgear:blue:wlan ) out hi
gpio-503 ( |netgear:amber:test ) out hi
gpio-504 ( |netgear:green:power ) out lo
gpio-505 ( |rfkill ) in hi
gpio-507 ( |wps ) in hi
gpio-508 ( |reset ) in hi
gpio-510 ( |ath9k-phy0 ) out hi <===!
The pin pointed above is default LED GPIO (8) for AR9287.
For WNR2200 it is not connected anywhere - pin 0 drives blue WLAN
LED instead - but initialization code is missing that information.
This fix calls ap9x_pci_setup_wmac_led_pin() function at device
setup, forcing WLAN LED pin to be 0 and removing redundant entry.
