imx8: postpone moving resources to non-secure partition
With flash_uboot_cm4ddr in imx-mkimage, the m4 code will access ddr.
However after m4 core moved to non-secure partition, the ddr memory
is still in secure partition. Then m4 core will fault.
So postpone moving resources including m4 core, until other resources,
such as memory/pin moved to non-secure partition.
