delay_detect in HZ is confusing, convert it to be millisecond based. And
thus remove those unnecessary call to msecs_to_jiffies() at runtime for
this field. Other constants are converted assuming HZ == 100, which are
basically true for those platforms.

The assignment in csb726.c was incorrect, and is fixed in this patch as
a result.
