drivers/perf: hisi: Consolidate uncore PMU cpuhp states

Every HiSilicon uncore PMU driver allocates its own static cpuhp state
even though they all register identical online/offline callbacks. This
wastes slots in the cpuhp state enum and needlessly fragments the
hotplug state space.

Move the cpuhp state setup into the shared hisi_uncore_pmu framework:
register a single dynamic state (CPUHP_AP_ONLINE_DYN) at framework
module init and export it for all HiSilicon uncore PMU drivers to use.
Drop the now-unused static CPUHP_AP_PERF_ARM_HISI_* entries from
include/linux/cpuhotplug.h.

The L3C PMU driver keeps a private dynamic state because it has its own
hotplug callbacks for migrating multiple per-CPU interrupt affinities,
but switches from its former static slot to CPUHP_AP_ONLINE_DYN for
consistency.

No intended functional changes.
