[Qemu-devel] [PATCH v6 14/37] spapr: modify the irq backend 'init' method

["Cédric Le Goater" <clg@kaod.org>]

Add a 'nr_irqs' parameter to the 'init' method to remove the use of
the machine class. This will be useful when we introduce the machine
supporting the two sPAPR IRQ backends : XICS and XIVE.
