mtd: nand: provide Linux' struct nand_ecc_ctrl::engine_type
The Linux MTD-NAND core doesn't seem to care much for the engine_type,
but different drivers use it to record during probe, which kind of
ECC engine should be used during future operation. Provide the member
to make porting drivers a tiny bit easier.
