drivers/perf: arm_pmu: Set readable_on_cpus for the perf event core ...

Although supported_cpus may indicate that the PMU counters can be read from
any CPU, the perf event core doesn't know that and instead resorts to
reading PMU counters on a specific CPU using costly IPIs.

Let perf know that the PMU counters can be read remotely by copying the
supported_cpus mask into readable_on_cpus.
