[LINUX PATCH v11 2/3] mtd: rawnand: Add an option to get sdr timing mode number

[Naga Sureshkumar Relli]

Some NAND controllers needs sdr timing mode value, instead of
timings parameters. i.e the NAND controller will change its operating
mode by just configuring the sdr timing mode number. so add mode parameter
in struct nand_sdr_timings.
