Fix sparse warning:

drivers/mtd/nand/raw/ingenic/ingenic_nand.c:140:32: warning:
 symbol 'jz4725b_ooblayout_ops' was not declared. Should it be static?

e787be1f1d 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.

If we want to use the generic NAND layer, we need to have the memorg
struct appropriately filled. Patch the detection code to fill this

e84950691b mtd: rawnand: ingenic: Move BBTs out of ECC area
The generic layout for BBT markers will most likely overlap with our
ECC bytes in the OOB, so move the BBT markers outside the OOB area.

3e6ac2ad90 mtd: rawnand: ingenic: Add support for the JZ4725B
The boot ROM of the JZ4725B SoC expects a specific OOB layout on the
NAND, so we use it unconditionally in the ingenic-nand driver.

Also add the jz4725b-bch driver to support the JZ4725B-specific BCH
hardware.

15de8c6efd mtd: rawnand: ingenic: Separate top-level and SoC specific code
The ingenic-nand driver uses an API provided by the jz4780-bch driver.
This makes it difficult to support other SoCs in the jz4780-bch driver.
To work around this, we separate the API functions from the SoC-specific
code, so that these API functions are SoC-agnostic.

d74fd06f44 mtd: rawnand: ingenic: Rename jz4780_bch_init to jz4780_bch_reset
The jz4780_bch_init name was confusing, as it suggested that its content
should be executed once at init time, whereas what the function really
does is reset the hardware for a new ECC operation.

The jz4780_nand driver will be modified to handle all the Ingenic
JZ47xx SoCs that the upstream Linux kernel supports (JZ4740, JZ4725B,
JZ4770, JZ4780), so it makes sense to rename it.
