Input: applespi - add dependency on LEDS_CLASS

If applespi is enabled, but LEDs class support is not, the build fails:

drivers/input/keyboard/applespi.o: In function `applespi_probe':
applespi.c:(.text+0x1fcd): undefined reference to `devm_led_classdev_register_ext'

Add "depends on LEDS_CLASS" to the Konfig
