arm/dts: hammerhead: Remove erroneous qcom,msm-bus,active-only property
qcom,msm-bus,active-only is a boolean and not an integer. As a
result, setting "active-only = <0>" was actually enabling it.

msm8974: Adapt memutils optimizations from msm8960pro

Preload farther to take advantage of the memory bus, and assume
64-byte cache lines.  Unroll some pairs of ldm/stm as well, for
unexplainable reasons.

Future enhancements should include,

- #define for how far to preload, possibly defined separately for
  memcpy, copy_*_user
- Tuning for misaligned buffers
- Tuning for memmove
- Tuning for small buffers
- Understanding mechanism behind ldm/stm unroll causing some gains
  in copy_to_user

msm: msm_rq_stats: Add proper attribute to enable hotplug

* hotplug_disable attribute resets when device suspend and
  sets when device resumes.
* Thereby, the value is dynamic. Perhaps, this value is read
  by userspace, so we don't want to mess with it further.
* Restore hotplug_disable to original format of read-only.
* Introduce hotplug_enable attribute which will do the job.
* We have "enable" attribute for other hotplug drivers, so
  this implementation aligns with them.
