Patch from: john stultz <johnstul@us.ibm.com>

        This patch "fixes" the timer_cyclone code by having it
initialize fast_gettimeoffset_quotient and cpu_khz in the same manner as
timer_tsc. This is required for enabling the timer_cyclone code on the
x440. 

Ideally fast_gettimeoffset_quotient would not be used outside timer_tsc
and cpu_khz would be initialized generically outside the timer
subsystem. I have patches to do this, but they touch quite a bit of
generic code, and I'd rather not make the timer_cyclone enablement
(patch to follow) depend on these larger changes.
