The nand-controller.yaml binding requires a child node (e.g. nand@0) under
the NAND controller. However, the driver currently assigns the controller's
of_node directly to the NAND chip.

Search for the first child node with the "nand" prefix and assign it to
chip->of_node. This filters out properties such as "partition" that may be
placed under the controller node in some older DTS files.

Fall back to using the controller's of_node if no suitable child node is
found to maintain backward compatibility.

This issue went unnoticed because the default behavior works for most NAND
chips.

Applied to nand/next, thanks!

Patche(s) should be available on mtd/linux.git and will be
part of the next PR (provided that no robot complains by then).

Kind regards,
