[LINUX PATCH v12 2/3] mtd: rawnand: Add an option to get sdr timing mode number

[Naga Sureshkumar Relli <naga.sureshkumar.relli@xilinx.com>]

Some NAND controllers need SDR timing mode value, instead of timings.
i.e the NAND controller will change its operating mode by
just configuring the sdr timing mode number. So add a mode field to
struct nand_sdr_timings
