ChangeLog v8->v9:
- Added the dtb target into arch/arm/boot/dts/Makefile.
- Added a blank line before the pcf8563 node in the i2c1 node.
- Whitespace cleanups as requested by Shawn Guo.
- _' was used in label, it's now fixed (it has been replaced with '-').
- The recently introduced defines for input and gpios are now used.
- The uarts had the fsl,uart-has-rtscts property set, but they didn't use 
  any rts and cts pins in the uart pinctrl nodes.

ChangeLog v7->v8:
- The commit message was improved.
- The board specific iomuxc pins group configuration that were in imx35.dtsi were moved here.
- The rest of the patch was updated accordingly.

ChangeLog v6->v7:
- Added Grant Likely in the Cc list.
- Shortened the license.
- The tsc2007 pads were moved in another patch.

ChangeLog v5->v6:
- Shawn Guo was added in the Cc.
