CPUFREQ: Loongson2: drop set_cpus_allowed_ptr()
It is pure mystery to me why we need to be on a specific CPU while looking up a value in an array. My best shot at this is that before commit d4019f0a92ab ("cpufreq: move freq change notifications to cpufreq core") it was required to invoke cpufreq_notify_transition() on a special CPU. Since it looks like a waste, remove it. Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Acked-by: Viresh Kumar <viresh.kumar@linaro.org> Cc: Rafael J.
