[PATCH 1/2] ARM: EXYNOS: Fix ARM PMU irq numbers

This patch fixes irq numbers of ARM PMU(Perfromance Monitoring Unit).
We need to seperate arm-pmu(performance measurement unit) and exynos-pmu(power
management unit). I decide to change EXYNOS4_IRQ_PMU to EXYNOS4_IRQ_POWER_PMU
because there are no one use it.
A max cpu number of exynos4 is four in case of exynos44xx. So we should define 3
additional pmu irq numbers and enable it according to the number of cpus.
