Make the phase synchronization of the hz clock interrupt (I8254 timer0)
to the timecounter more generic.  This will work with all time counters
as long as the 8254's crystal isn't to terribly off, but it could take a
few minutes for the computer to lock the phase after boot.  I'm being
conservative here and do not want to skew the clock interrupt too much.

Tested by: Paul Herman <pherman@frenchfries.net>
