    realtek: remove hardcoded sys-led configurations
    
    setup.c unconditionally sets the sys-led mode (blinking rate) to a
    permanent high output. This may cause issues when a board expects this
    pin to toggle periodically, e.g. when hooked up to an external watchdog.
    
    If the sys-led peripheral is used to control an LED, the mux should be
    configured to use the pin as GPIO0, allowing for better control as a
    GPIO LED.
