arm64: dts: rockchip: Update leds for Anbernic RGxx3 Series

Browse Source 
Each of the LEDs on the RGxx3 which is currently controlled via GPIO
can also be controlled via a PWM. Change each of the LEDs to PWM so
that users have the ability to adjust the brightness of the LEDs
according to their preference.
