mtd: nand: Pass mode information to nand_page_io_req

Browse source 
The NAND sub-layers are likely to need the MTD_OPS_XXX mode information
in order to decide if they should enable/disable ECC or how they should
place the OOB bytes in the provided OOB buffer.

Add a field to nand_page_io_req to pass this information.
