Subject: [PATCH v2] Input: applespi - Fix build error

If CONFIG_KEYBOARD_APPLESPI=y but CONFIG_LEDS_CLASS=m
building 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
