From: Muhammed Efe Cetin <efectn@xxxxxxxxxxxxxx>
Khadas Edge 2 exposes IR receiver pins as same as TF card via EXTIO. The
IR receiver is connected to MCU and SoC.
The board also has 2 PWM RGB leds. One is controlled by MCU and the
other is controlled by SoC. This commit adds support for the led
controlled by SoC using pwm-leds.
