[PATCH v4 01/10] arm64: topology: Use scope-based cleanup helper

[Zihuan Zhang]

Replace the manual cpufreq_cpu_put() with __free(put_cpufreq_policy)
annotation for policy references. This reduces the risk of reference
counting mistakes and aligns the code with the latest kernel style.

No functional change intended.
