 timecounter: Merge FreeBSD change r324528

 The th_bintime, th_microtime and th_nanotime members of the timehand all
 cache the last system time (uptime + boottime). Only the format differs.
 Do not re-calculate the bintime and simply use the value used to calculate
 the microtime and nanotime.

 Group all the updates under the relevant comment.  Remove obsoleted
 XXX part.
