ian ae3d035140 Improve the performance of the hpet timer in bhyve guests by making the ...

timer frequency a power of two.  This changes the frequency from 10 to
16.7 MHz (2 ^ 24 HZ).  Using a power of two avoids roundoff errors when
doing arithmetic in sbintime_t units.

Testing shows this can fix erratic ntpd behavior in guests using the
hpet timer (which is the default for multicore guests).
