dt-bindings: mtd: nand-controller: Fix a comment in the examples

commit 0e7f1b55 upstream.

The controller properties should be in the controller 'parent' node,
while properties in the children nodes are specific to the NAND
*chip*. This error was already present during the yaml conversion.

Fixes: 2d472aba
