sabre: increase number of PCI bus IRQs from 32 to 64
The rework of the sabre IRQs in commit6864fa3897
"sun4u: update PCI topology to include simba PCI bridges" changed the IRQ routing so that both PCI and legacy OBIO IRQs are routed through the sabre PCI host bridge to the CPU. Unfortunately this commit failed to increase the number of PCI bus IRQs accordingly meaning that access to the legacy IRQs OBIO (irqnum >= 0x20) would overflow the PCI bus IRQ array causing strange failures running qemu-system-sparc64 in NetBSD.
