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.
