Johannes Schmitz 523688ae5c board/ci20: create a SD card image
Add a genimage.cfg to create a working sdcard.img for the ci20
hardware.  We also need a uboot-env.txt to create the partition for
the uboot environment.

Update the board/ci20/readme.txt with the related information. Remove
the tftp netboot description from the readme as it is already to
complicated for a basic bootable example.
