ChangeLog v3->v5:
- Updated to the new GPIO defines.

ChangeLog v2->v3:
- Splitted out from the patch that added support for the cpuimx51/mbimxsd51 boards.
- This patch now only adds backlight support.
- Added some interested people in the Cc list, and removed some people that
  might be annoyed by the receiving of that patch which is unrelated to their
  subsystem.
