The nand-controller schema enforces specific node naming. Adjust the
existing DTs instead of modifying the YAML schema to match legacy layouts.

Update the DTs to follow the modern NAND controller layout, which has
been used in the MTD subsystem for many years.

Applied to nand/next, thanks!

[1/3] dt-bindings: mtd: mxc-nand: add i.MX25 and i.MX27 nand support
      commit: d86e70e9ca995942e848515b089e9be7430c862e

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,
Miquèl
