Added some CPU hotplug governors:

- Mako hotplug governor
- Alucard hotplug governor
- MSM Sleeper hotplug governor
- Zen Decision hotplug governor

- Blu_plug can be enabled/disabled via sysfs now,
  so only one kernel build this time.

Added support for ARM Neon in kernel mode and some crypto algorithms now use the NEON extensions

Added MDSS color control and faux wcd93xx sound control hax to the kernel.
