Now that all the logic is available in the NAND core, let's use it from the SPI-NAND core. Right now there is no functional change as the default ECC engine for SPI-NANDs is set to 'on-die', but user can now use software correction if they want to by just setting the right properties in the DT. Also note that the OOB layout handling is removed from the SPI-NAND core as each ECC engine is supposed to handle it by it's own; users should not be aware of that.
