int3472 now fails to link when the LED support is disabled:
x86_64-linux-ld: drivers/platform/x86/intel/int3472/led.o: in function `skl_int3472_register_pled':
led.c:(.text+0xf4): undefined reference to `led_classdev_register_ext'
x86_64-linux-ld: led.c:(.text+0x131): undefined reference to `led_add_lookup'
x86_64-linux-ld: drivers/platform/x86/intel/int3472/led.o: in function `skl_int3472_unregister_pled':
led.c:(.text+0x16b): undefined reference to `led_remove_lookup'
x86_64-linux-ld: led.c:(.text+0x177): undefined reference to `led_classdev_unregister'
Add an explicit Kconfig dependency.
