Dove: Fix irq_to_pmu()
commit d356cf5a74afa32b40decca3c9dd88bc3cd63eb5 upstream. PMU interrupts start at IRQ_DOVE_PMU_START, not IRQ_DOVE_PMU_START + 1. Fix the condition. (It may have been less likely to occur had the code been written "if (irq >= IRQ_DOVE_PMU_START" which imho is the easier to understand notation, and matches the normal way of thinking about these things.)
