[PATCH] arm: perf: Set affinity for PPI based PMUs

For PPI based PMUs, we bail out early in of_pmu_irq_cfg() without setting the PMU's supported_cpus bitmap. This causes the smp_call_function_any() in armv7_probe_num_events() to fail. Set the bitmap to be all CPUs so that we properly probe PMUs that use PPIs. Fixes: cc88116da0d1 ("arm: perf: treat
