ARM: 7448/1: perf: remove arm_perf_pmu_ids global enumeration
In order to provide PMU name strings compatible with the OProfile user ABI, an enumeration of all PMUs is currently used by perf to identify each PMU uniquely. Unfortunately, this does not scale well in the presence of multiple PMUs and creates a single, global namespace across all PMUs in the system. This patch removes the enumeration and instead uses the name string for the PMU to map onto the OProfile variant. perf_pmu_name is implemented for CPU PMUs, which is all that OProfile cares about anyway.
