configs/imx6-sabreauto: Add a new defconfig



Introduce imx6-sabreauto_defconfig that uses mainline U-Boot and
mainline kernel.

As mainline U-Boot supports SPL, it is possible to boot the same
sdcard.img in the three mx6sabreauto variants: imx6q, imx6dl and imx6qp.

Also update the readme.txt file to explain how to build an image for
mx6sabreauto boards using mainline U-Boot and kernel.
