On spapr, the max number of CPU IPIs are 4096 which is accounted during
spapr_irq_init but currently existing macro SPAPR_XIRQ_BASE is being
used to refer to that. Introducing SPAPR_IRQ_NR_IPIS to refer to the
range
of CPU IPIS which is being further used to initialize mc->max_cpus
during spapr_machine_class_init().
