drivers/perf: hisi: Schedule perf session according to locality
The PCIe PMUs locate on different NUMA node but currently we don't
consider it and likely stack all the sessions on the same CPU:
[root@localhost tmp]# cat /sys/devices/hisi_pcie*/cpumask
0
0
0
0
0
0
This can be optimize a bit to use a local CPU for the PMU.
