[POWERPC] Use __get_cpu_var in time.c
Use __get_cpu_var(x) instead of per_cpu(x, smp_processor_id()), as it
is optimized on ppc64 to access the current cpu's per-cpu offset directly;
it's local_paca.offset instead of TOC->paca[local_paca->processor_id].offset.
This is the trivial portion, two functions with one use each.
