The CMO-QVGA, DVI-VGA and DVI-SVGA displays were added.

Signed-off-by: Denis Carikli <denis at eukrea.com>
---
ChangeLog v15->v16:
- Added the dtb targets in the Makefile.
- Removed the redundant enable-active-high.
- Simplified the commit description.

ChangeLog v14->v15:
- Moved the Cc into git-send-email.
- Added a reg property in the regulator at 0 node.

ChangeLog v13->v14:
- Remove people not concerned by this patch from the Cc list.
- changed the fsl,pwmr lcdc property to fsl,lpccr,
  to match the previous patches in that serie.

ChangeLog v10->v13:
- This patch is the display part splitted out from the patch adding
  support for the cpuimx25(and its baseboard).
- Shawn Guo was added to the Cc list.
- The regulator part was updated to match the current style.
- The new GPIO defines are now used in the dts(i).
