    openrisc: Set shortest clock event to 100 ticks · 754d5c2b

    It takes a couple of instructions to actually configure a clock event
    so setting an alarm just 1 clock cycle in the future isn't going to work;
    doing so results in setting an alarm in the "past" in which case the event
    won't fire until the timer overflows and rolls back around to the "current
    time".
    
    Not quite sure how many clock cycles it actually takes to get through to
    actually writing the register, but 100 seems to work reliably.
    
    Use generic helper to set up the clock event while we're at it.
