mtd: nand: qpic-common: add defines for ECC_MODE values
Add defines for the values of the ECC_MODE field of the NAND_DEV0_ECC_CFG
register and change both the 'qcom-nandc' and 'spi-qpic-snand' drivers to
use those instead of magic numbers.
No functional changes. This is in preparation for adding 8 bit ECC strength
support for the 'spi-qpic-snand' driver.
