net: dsa: qca8k: fix LEDS_CLASS dependency

With LEDS_CLASS=m, a built-in qca8k driver fails to link:

arm-linux-gnueabi-ld: drivers/net/dsa/qca/qca8k-leds.o: in function `qca8k_setup_led_ctrl':
qca8k-leds.c:(.text+0x1ea): undefined reference to `devm_led_classdev_register_ext'

Change the dependency to avoid the broken configuration.
