ACPI: processor: thermal: avoid cpufreq_get_policy()
cpu_has_cpufreq() stores a 'struct cpufreq_policy' on the stack.
Unfortunately, with debugging options enabled, the structure can be
larger than 1024 bytes, which causes a compiler warning/error.
(actually observed: 1184 bytes).
Therefore: Switch to cpufreq_cpu_get().
