[PATCH v6 09/28] dt-bindings: spi: mxic: Document the nand-ecc-engine property

[Miquel Raynal]

This SPI controller supports interacting with an external ECC
engine. The nand-ecc-engine property already exist in the NAND world but
also applies to SPI controller nodes which have external correction
capabilities like Macronix's.
