[PATCH] ppc64: consolidate calibrate_decr implementations
pSeries and maple have almost the same code for calibrate_decr, and BPA would need yet another copy. Instead, I'm moving the code to arch/ppc64/kernel/time.c. Some of the related declarations were missing from header files, so I'm moving those as well. It makes sense to merge this with the pmac function of the same name, so we end up having just one implemetation for iSeries and one for Open Firmware based machines.
