Changes in v2:
- Create an imx23-olinuxino-u-boot.dtsi with the u-boot-specific changes
  instead of modifying the imx23-olinuxino.dts file (which comes directly from
  the Linux kernel). This helps preserve the ability to directly import the
  Linux kernel device tree files into U-Boot without modification.
