Humm, seems that was to describe partitions, but the expectation of
the nand binding is describing nand chips. It seems the nand chips are
never described and on 1 board even has partitions. I think you should
fix the dts to move 'partition@N' nodes under 'partitions' which is
preferred and needed if you ever describe nand chips. And then fix
'#size-cells' to be 0.
