Now that most of the raw NAND API is consistent and has almost all its
helpers and hooks using a single nand_chip object instead of an mtd_info
one (or both), let's do the same cleanup in the raw NAND vendors
drivers.
Apply this change to the Toshiba driver so that the internal helper to
retrieve the ECC status does only take a nand_chip object.

A lot of things defined in rawnand.h should not be exposed to NAND
controller drivers and should only be shared by core files.
Create the drivers/mtd/nand/raw/internals.h header to store such
definitions, and move all private defs to this header.
Also remove EXPORT_SYMBOLS() on functions that are not supposed to be
exposed.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle all ecc->read_xxx() hooks at once.

This patch is a patch to support TOSHIBA MEMORY CORPORATION BENAND
memory devices. Check the status of the built-in ECC with the Read
Status command without using the vendor specific command. The Read
Status command only knows whether there was bitflips above the
threshold and can not get accurate bitflips. For now, I set
max_bitflips mtd->bitflip_threshold.

As part of the process of sharing more code between different NAND
based devices, we need to move all raw NAND related code to the raw/
subdirectory.
