Add a mechanism to handle the case in which partitions are present as direct child of the nand controller node and #size-cells is set to <0>.
This could happen if the nand-controller node in the DTS is supposed to have #size-cells set to 0, but for some historical reason/bug it was set to 1 in the past, and the firmware (e.g. U-Boot) is adding the partition as direct children of the nand-controller defaulting to #size-cells being to 1.
This prevents a real boot failure on colibri-imx7 that happened during v6.1 development cycles.

Miquel, Marek: I do not expect this patch to be backported to stable, however I would expect that we do not backport nand-controller dts cleanups neither.
Okay.

mtd_node);
Why mtd_node on a new line?
For some historical reason most of this file is like that, so I did the same for consistency (to be honest when I did it I though it was _all_ like that).
Otherwise looks good to me.
I can send a v2 with this changed.
Yes please.
Thanks for the U-Boot series by the way.
Thanks, Miquèl
