Pawel Dembicki a254279a6c layerscape: Change to combined rootfs on sd images
At this moment layerscape images are ext4 only. It causes problem with
save changes durring sysupgrade and make "firstboot" and failsafe mode
useless.

This patch changes sd-card images to squashfs + f2fs combined images.
To make place, for saving config, kernel space ar now ext4 partition
with fit kernel.

This method of image generation is similar to rest of OpenWrt sd-card
targets.

DEVICE_COMPAT_VERSION := 2.0
DEVICE_COMPAT_MESSAGE := DTB was added to sysupgrade. Image format is different. \
To use sysupgrade You need to change firmware partition in bootargs to "49m@0xf00000(firmware)" and saveenv. \
After that, You can use "sysupgrade -F".

It is required to flash the entire sd-card again and manually copy config.
