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.

6f84b26b53 mtd: nand: Add a few more timings to nand_sdr_timings
Add the tR_max, tBERS_max, tPROG_max and tCCS_min timings to the
nand_sdr_timings struct.
Assign default/safe values for the statically defined timings, and
extract them from the ONFI parameter table if the NAND is ONFI
compliant.

b893e83330 mtd: nand: Expose data interface for ONFI mode 0
The nand layer will need ONFI mode 0 to use it as timing mode
before and right after reset.

46deff57da mtd: nand: convert ONFI mode into data interface
struct nand_data_interface is the designated type to pass to
the NAND drivers to configure the timing. To simplify further
patches convert the onfi_sdr_timings array from type struct
nand_sdr_timings nand_data_interface.

d3963721d9 nand: Sync with Linux v4.1
Update the NAND code to match Linux v4.1.  The previous sync was
from Linux v3.15 in commit 4e67c57125.

CONFIG_SYS_NAND_RESET_CNT is removed, as the upstream Linux code now
has its own timeout.  Plus, CONFIG_SYS_NAND_RESET_CNT was undocumented
and not selected by any board.
