[U-Boot] [PATCH v3 12/21] mtd: nand: Pass mode information to nand_page_io_req

[Miquel Raynal]

From: Boris Brezillon <boris.brezillon at bootlin.com>

The NAND sub-layers are likely to need the MTD_OPS_XXX mode information
in order to decide if they should enable/disable ECC or how they should
place the OOB bytes in the provided OOB buffer.

Add a field to nand_page_io_req to pass this information.
