[PATCH v2 1/2] ppc/spapr: Introduce SPAPR_NR_IPIS to refer IRQ range for CPU IPIs.

[Harsh Prateek Bora <harshpb@linux.ibm.com>]

spapr_irq_init currently uses existing macro SPAPR_XIRQ_BASE to refer to
the range of CPU IPIs during initialization of nr-irqs property.
It is more appropriate to have its own define which can be further
reused as appropriate for correct interpretation.
