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

Revert "backlight: clean the code."

This reverts commit 58ed09410feabc1107b7aeed4fa85f27cb56d791.
Revert "backlight: fix a bug where the screen would be completely dark or near darkness with backlight_dimmer enabled when the display dimmed. The brightness level can't be any lower than dev->min_brightness and previous code allowed that to happen, so fix it."

This reverts commit b5e8a8959f0fc996ba1934d0fd807ec82f5e36d4.
