mtd: nand: mxic-ecc: Add Macronix external ECC engine support
Some SPI-NAND chips do not support on-die ECC. For these chips,
correction must apply on the SPI controller end. In order to avoid
doing all the calculations by software, Macronix provides a specific
engine that can offload the intensive work.
Add Macronix ECC engine support, this engine can work in conjunction
with a SPI controller and a raw NAND controller, it can be pipelined
or external and supports linear and syndrome layouts.
Right now the simplest configuration is supported: SPI controller
external and linear ECC engine.
