[PATCH 3/3] drivers/perf: hisi: Add cycle event for HIP13 MN PMU

[Yushan Wang]

From: Yifan Wu <wuyifan50 at huawei.com>

The MN (Miscellaneous Node) PMU on HiSilicon HIP13 exposes a cycle
counter in addition to the existing event set. Add a v2 event list
that includes the cycles event (0x0F) and a new hisi_mn_v2 dev_info
matched by the new ACPI id HISI0224.

Rename the existing event list, attribute group and attr_groups array
to *_v1 so the two MN PMU versions can coexist.
