All devices that can use the system LED peripheral to control an actual
LED currently use this as a GPIO-controlled LED. A GPIO LED provides
more fine-grained control of blink rates, at the cost of some CPU
cycles. Users may anyhow prefer to use the sys-led peripheral, so add
the sys-led node as "disabled".
