drivers/perf: hisi: Migrate to one online CPU if no associated one online
If the selected CPU hisi_pmu::on_cpu goes offline, driver will select
a new online CPU from hisi_pmu::associated_cpus, or if no online CPU
found the PMU context won't be migrated. However for uncore PMUs the
associated CPUs are just a peference and it also works to schedule
the events on any online CPUs. So add a fallback to choose an online
CPU if no associated CPUs found.
