    rockchip: show boot stages on nanopi R6 system LED
    
    Set up openwrt to show boot progress on the nanopi R6S or R6C system LED.
    
    The LED blinking states indicate the boot stage. The LED is defined as
    a power LED, but can still be set to heartbeat in /etc/config/system
    after the system is done booting.
