Subject: [PATCH 0/3] ARM: dts: imx: clean up imx2* NAND CHECK_DTBS warnings

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.
