led-class.c: quiet boot messages

As each led device gets registered a kernel message gets printed. In
an embedded system with a number of leds this can produce a lot
of output that just looks like noise.

Change the message type to KERN_DEBUG since it might be useful
in the dmesg output "after" booting.
