sched/cputime, powerpc: Prepare accounting structure for cputime flush on tick
In order to prepare for CONFIG_VIRT_CPU_ACCOUNTING_NATIVE=y to delay
cputime accounting to the tick, provide finegrained accumulators to
powerpc in order to store the cputime until flushing.
While at it, normalize the name of several fields according to common
cputime naming.
