brcmsmac: Fix build dep on LEDS_CLASS

When building randconfigs with CONFIG_BCMA_DRIVER_GPIO=y, I get

drivers/built-in.o: In function `brcms_led_unregister':
(.text+0x351aca): undefined reference to `led_classdev_unregister'
drivers/built-in.o: In function `brcms_led_register':
(.text+0x351c65): undefined reference to `led_classdev_register'

during final linking stage because brcmsmac/led.c needs LEDS_CLASS for
registering/deregistering the led device. Select the required symbols.
