ARM: perf: replace global CPU PMU pointer with per-cpu pointers
A single global CPU PMU pointer is not useful in a system with multiple, heterogeneous CPU PMUs as we need to access the relevant PMU depending on the current CPU. This patch replaces the single global CPU PMU pointer with per-cpu pointers and changes the OProfile accessors to refer to the PMU affine to CPU0.
