[PATCH v4 16/21] dt-bindings: mtd: Deprecate the nand-ecc-mode property

[Miquel Raynal <miquel.raynal@xxxxxxxxxxx>]

This property does not describe very well its purpose: it describes
the ECC engine type, also called provider. Deprecate it in favor of
nand-ecc-provider. In the mean time, update a bit the description of
the property to make it more accurate.
