Masahiro Yamada 6ae3900a86 mtd: nand: Rename nand.h into rawnand.h
This header was renamed to rawnand.h in Linux.

The following is the corresponding commit in Linux.

      mtd: nand: Rename nand.h into rawnand.h

      We are planning to share more code between different NAND based
      devices (SPI NAND, OneNAND and raw NANDs), but before doing that
      we need to move the existing include/linux/mtd/nand.h file into
      include/linux/mtd/rawnand.h so we can later create a nand.h header
      containing all common structure and function prototypes.
