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.
