    mediatek: fix TUF-AX4200 WAN LED
    
    With the current LED configuration using "mxl,led-config", the WAN LED
    stops working after the interface is brought down and up again.
    
    Since the driver also properly supports PHY LEDs now, switch to that
    instead. This makes the LED work properly, but requires configuration
    from userspace.
    
    Fixes: #17782
