REVERT : 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

2-way stereo call recording patch for msm8974

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.
