[PATCH resend] mtd: spinand: Propagate ECC information to the MTD structure

[Miquel Raynal <miquel.raynal@xxxxxxxxxxx>]

This is done by default in the raw NAND core (nand_base.c) but was
missing in the SPI-NAND core. Without these two lines the ecc_strength
and ecc_step_size values are not exported to the user through sysfs.

This fix depends on recent changes and should not be backported as-is.

This patch is extracted from a bigger series and needs to be merged
now as a fix. I haven't changed anything from it's original
submission.
