powerpc/mpic: Fix regression caused by change of default IRQ affinity
The Freescale implementation of MPIC only allows a single CPU destination for non-IPI interrupts. We add a flag to the mpic_init to distinquish these variants of MPIC. We pull in the irq_choose_cpu from sparc64 to select a single CPU as the destination of the interrupt. This is to deal with the fact that the default smp affinity was changed by commit 18404756765c713a0be4eb1082920c04822ce588 ("genirq: Expose default irq affinity mask (take 3)") to be all CPUs.
