Just make them variables, and compute them ONCE during boot.
ppc calls calibrate_decr() before enabling the timer interrupt anyways.
time_nsec is easy.
in a platfrom specific file do (very simplified):
extern unsigned long time_nsec;
time_nsec = REAL_TIME_NSEC;
This (of course) will do nothing about LATCH and ACTHZ that might be
used other places.
