changes in v5:
1. Fix typo: enynos_pmu_cpunr -> exynos_pmu_cpunr
changes in v4:
1: Dropped changes in platsmp.c and hotplug.c as those are taken care by
Tomasz Patches.
2. Converted ENYNOS_PMU_CPUNR macro to static inline function
changes in v3:
1. Move cpunr calculation to a macro
2. Changed printk format specifier from unsigned hex to unsigned decimal
Changes in v2:
1. Used existing macros for clusterid and cpuid calculation
