The mpc8xx driver uses a reference to NR_IRQS that is buggy. It uses NR_IRQs for the array size of the ppc_cached_irq_mask bitmap, but NR_IRQs could be smaller than the number of hardware irqs that ppc_cached_irq_mask tracks. Also, while fixing that problem, it became apparent that the interrupt controller only supports 32 interrupt numbers, but it is written as if it supports multiple register banks which is more complicated. This patch pulls out the buggy reference to NR_IRQs and fixes the size of the ppc_cached_irq_mask to match the number of HW irqs. It also drops the now-unnecessary code since ppc_cached_irq_mask is no longer an array.
