x86 platform drivers: make Dell laptop driver select needed LED support
Otherwise we get compile errors like this:
ERROR: "led_classdev_unregister" [drivers/platform/x86/dell-laptop.ko] undefined!
ERROR: "led_classdev_register" [drivers/platform/x86/dell-laptop.ko] undefined!
make[1]: *** [__modpost] Error 1
make: *** [modules] Error 2
when the dell-laptop support is enabled without the necessary LED
support being enabled.
