You're right, BCMA_DRIVER_GPIO doesn't need LEDS_CLASS.

So, the only solution I can think of right now is below, maybe
adding a hidden config symbol CONFIG_BRCMSMAC_LEDS which depends on
BCMA_DRIVER_GPIO and LEDS_CLASS and then doing:

brcmsmac-$(CONFIG_BRCMSMAC_LEDS) += led.o

would be cleaner though. I could try that out tomorrow.
