"Where it is connected" is not interesting to the userland. "Is it
backlight for internal keyboard" is the right question. It may be
connected to embedded controller or some kind of controller over
i2c... my shell scripts should not need to know about architecture of
every notebook out there.

But I don't see why I should do additional work when its trivial for
kernel to just name the LED in an useful way.

"platform::kbd_backlight" has no disadvantages compared to
"wilco::kbd_backlight" ... so lets just use it.
