cpufreq: cpu-boost: Fix cores getting stuck. Finally.

* In exclusive hotplug system, if a core is not taken down
  explicitly, it is observed that it gets stuck at input
  boost frequency.
* This issue maybe particular to only this kernel but this
  fix resolves it completely.
* Root cause seems to be removal work is lost if queued on
  sibling cores. So simply fix this by queuing on boot CPU.

* Finally, I can use min_cpus_online > 1 without any issue.

stereo call recording support

Patch that allows for call recording in
stereo (left channel: TX; right channel:
RX). Tested on Nexus 5 (MSM8974). Likely
works on other recent MSM chipsets as
well.
