layerscape: ls1012afrdm: introduce dynamic partitioning
Combine fixed sizes of "kernel" and "rootfs" partitions into one partition managed by OpenWrt splitter, it will allow better management of chip capacity and less maintenance burden when compiled kernel image will outgrow allocated size for kernel partition. This also changes kernel image format, since splitter only manages kernel and rootfs partitions, the dtb needs to be updated with the kernel, so for convenience, kernel is packed to FIT image.
