D'oh. Indeed it hurts on Nand. I assumed that this is a MMC partition.
There is no 1MiB requirement on Nand and we do not have a partition
table on Nand which may conflict with the device tree partitions.

Since this is i.MX25 and the imx_defconfig doesn't (yet) build so big
images I will drop this hunk for now.
