[PATCH v9 1/9] mtd: nand: Create a helper to extract the ECC configuration

[Miquel Raynal <miquel.raynal@xxxxxxxxxxx>]

Despite its current name "eccreq", this object first stores data that
is meant to be the requirements, and then this data gets eventually
updated and becomes the actual configuration. Abstracting this
indirection will help us clarify the structures in a future change.
