Subject: [PATCH v4 1/9] ARM: EXYNOS: removing redundant code from regs-pmu.h

commit 6ec4f8d0d91f ("ARM: EXYNOS: add generic function to calculate
cpu number") introduced exynos_pmu_cpunr to be used by multi-cluster SoC's
e.g Exynos5420, but it's no more used in the codebase and hence removing
this part of code.
