This patchset fixes irq numbers of ARM Performance Monitoring unit.
We need to seperate arm-pmu(performance measurement unit) and exynos-pmu(power
management unit). The exynos4 and 5 use 2 more cpu core which has its own pmu.
We should define pmu irq numbers according to the number of cpus.
The pmu irq of exynos4 and 5 uses combiner-irq type. To enable perf(performance
counter), we need to implement a set_irq_affinity function about the combiner-irq.

  ARM: EXYNOS: Add set_irq_affinity function for combiner_irq
