    atkbd: remove unused code that measures inb() duration
    
    We are not using the retry count as FreeBSD does.
    
    Instead, we are using TOTALDELAY / CHECKTIMEOUT, which measures the
    actual execution time after each loop iteration and breaks out of the
    loop when the total time (70ms or 200ms in most cases) has expired.
