ChangeLog v9->v10:
- Added Fabio Estevam To the Cc list

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.

Create pinctrl entry for gpio-leds and gpio-keys to contain them just
like other devices, and move ESDHC CD pin into esdhc1grp, so that we do
not need this hoggrp.  The hoggrp should only hold the pins that do not
really belong to any client devices.

Split it into two lines, one macro each.
