kgsl: disable tracing and postmortem
msm: cpufreq: Ensure cpufreq change happens on corresponding CPU

* This removes stuttering a few ppl were experiencing -imoseyon

Checking the cpus_allowed mask of the current thread before changing the
frequency doesn't guarantee that the rest of the execution will continue on
the same CPU. The only way to guarantee this is to schedule a work on the
specific CPU and also prevent hotplug  of that CPU (already done by
existing code).
