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().

v4: added "Reported-by" and "Tested-by" from Kowshik
v3: addressed further review comments from Cedric
v2: addressed review comments from Cedric

Harsh Prateek Bora (2):
  ppc/spapr: Introduce SPAPR_IRQ_NR_IPIS to refer IRQ range for CPU
