  To: buildroot

Add a standard genimage script for the MXS processors (MX23 and MX28).

Based on the common scripts for the other imx devices:
board/freescale/common/genimage.cfg.template
board/freescale/common/post-image.sh

This makes it easier to add new MX23/MX28 boards configurations into
Buildroot.
