Yicong Yang 555c6e9b03 drivers/perf: hisi: Set correct IRQ affinity for PMUs with no association 
For PMUs with no association, the hisi_pmu->on_cpu is initialized
according to the NUMA locality but use a wrong CPU for the interrupt
affinity. The CPU selected from cpumask_local_spread() can be different
from the CPU by the cpuhp callback. Fix this by setting the IRQ affinity
to hisi_pmu->on_cpu.
