powerpc/irq: Move __softirq_pending out of irq_stat

Browse Source 
__softirq_pending isn't part of arch specific irq_stats. It is used
by softirq core for various decision making such as whether to kick off
ksoftirqd.

Move it out of irq_cpustat_t. This makes it simple to make irq_cpustat_t
array based approach.
