mtd: rawnand: Change Kconfig titles and re-order a bit the list
This list is a mess, while some items should probably not be in the raw/ sub-directory, others are definitely at the right place but not with the right description. Write uniform titles and group IPs by vendor. NAND controllers will appear under the list named "Raw/parallel NAND flash controllers" while the other drivers will appear under "Misc". Software ECC engines will later be moved out of the raw/ directory. Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>

- On DiskOnChip devices shipped with the INFTL filesystem (Millennium

- data on your device (created by non-Linux tools such as M-Systems'
- DOS drivers), your data might overlap the area Linux wants to use for
- the BBT. If this is a concern for you, leave this option disabled and
- Linux will not write BBT data into this area.
- The downside of leaving this option disabled is that if bad blocks
- are detected by Linux, they will not be recorded in the BBT, which
- could cause future problems.
- Once you enable this option, new filesystems (INFTL or others, created
- in Linux or other operating systems) will not use the reserved area.
- The only reason not to enable this option is to prevent damage to
- preexisting filesystems.
- Even if you leave this disabled, you can enable BBT writes at module
- load time (assuming you build diskonchip as a module) with the module
- parameter "inftl_bbt_write=1".
