List of pwm-leds nodes. These are expected to have a pwms property
pointing to the relevant PWMs, in red, green, blue and optionally sidesel
order.
For example
pwmleds {
compatible = "pwm-leds";
pwm_led0: pwm_led_0 {
pwms = <&led3_red
&led2_green
&led1_blue
&led3_sidesel

compatible = "cros-ec,pwm-leds";
leds = <&pwm_led0>;
};
