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 d4019f0a ("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.
