Subject: [PATCH] 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.)
