I got a build error today, since LEDS_VERSATILE can be built-in while LEDS_CLASS
is a module:

drivers/built-in.o: In function `versatile_leds_probe':
:(.text+0x155020): undefined reference to `led_classdev_register'

I suggest we turn this option into 'tristate' so that the dependency
tracking works correctly.
