To be able to check and set bad block markers in the first and
second page of a block independently of each other, we create
separate flags for both cases.
Previously NAND_BBM_SECONDPAGE meant, that both, the first and the
second page were used. With this patch NAND_BBM_FIRSTPAGE stands for
using the first page and NAND_BBM_SECONDPAGE for using the second
page.
This patch is only for preparation of subsequent changes and does
not implement the logic to actually handle both flags separately.

The information about where the manufacturer puts the bad block
markers inside the bad block and in the OOB data is stored in
different places. Let's move this information to nand_chip.options
and nand_chip.badblockpos.
As this chip-specific information is not directly related to the
bad block table (BBT), we also rename the flags to NAND_BBM_*.

Make sure we flag all 1.8V broken chips as not supporting this feature.

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.

Make sure we flag all broken chips as not supporting this feature.
Also move this logic to a new function to keep things readable.

The MX30LF2G18AC chip declares in its parameter page supporting
SET/GET_FEATURES but when it comes to timings, experience shows that it
is not the case.
Unflag this feature for this particular chip in the nand_parameters
structure to avoid unnecessary errors and downturns.

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/
