ChangeLog v5->v6:
- Reordered the Cc list.

ChangeLog v3->v5:
- Updated to new GPIO defines.
- Updated to new licenses checkpatch requirements.
- one whitespace cleanup.

ChangeLog v2->v3:
- Splitted out from the patch that added support for the cpuimx51/mbimxsd51 boards.
- This patch now only adds display 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.
- rebased and reworked the dts displays addition.
- Also rebased and reworked the fsl,pins usage.
