    realtek: use higher priority for timer interrupts
    
    The assigned output index for the event timers was quite low, lower even
    than the ethernet interrupt. This means that high network load could
    preempt timer interrupts, possibly leading to all sorts of strange
    behaviour.
    
    Increase the interrupt output index of the event timers to 5, which is
    the highest priority output and corresponds to the (otherwise unused)
    MIPS CPU timer interrupt.
