The top level DT node of pwm-leds is not a LED itself, bind NOP uclass driver to it, and bind different LED uclass driver to its subnodes which represent the actual LEDs. This change removes the top-level node from the 'led list' command output and is based on the commit 01074697801b ("led: gpio: Use NOP uclass driver for top-level node").
