[Buildroot] [PATCH 2/5] freescale: genimage: Use the common genimage template

Sat Jul 9 06:40:01 UTC 2016
The boards imx6dlsabreauto, imx6dlsabresd, imx6qsabreauto, imx6qsabresd,
imx6sxsabresd were referring to board/freescale/create-boot-sd.sh for
the sdcard image generation:
* Remove board/freescale/create-boot-sd.sh
* Use the common Freescale genimage template instead.
The offset of the first partition was 1MB in the script and is
modified to 8MB in the template.
* Fix the readme.txt file accordingly
