[Trevor Woerner]

Convert the Olimex Olinuxino board's support for MMC to driver model following
Fabio Estevam's excellent example from:

	mx23evk: Convert to driver model

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.
