board/freescale: use the common genimage template

Browse Source 
The boards imx6dlsabreauto, imx6dlsabresd, imx6qsabreauto, imx6qsabresd,
imx6sxsabresd were referring to board/freescale/create-boot-sd.sh for
the sdcard image generation.

This commit:
* Removes board/freescale/create-boot-sd.sh
* Uses 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.
* Fixes the readme.txt file accordingly

@ -62,12 +62,16 @@ To determine the device associated to the SD card have a look in the
cat /proc/partitions
Run the following script as root on your SD card. This will partition the card
and copy the bootloader, kernel, DTBs and root filesystem as needed.
Buildroot prepares a bootable "sdcard.img" image in the output/images/
directory, ready to be dumped on a microSD card. Launch the following
command as root:
dd if=./output/images/sdcard.img of=/dev/<your-microsd-device>
*** WARNING! The script will destroy all the card content. Use with care! ***
./board/freescale/create-boot-sd.sh <your-sd-device>
For details about the medium image layout, see the definition in
board/freescale/common/genimage.cfg.template.
Boot the SABRE board
