SET/GET FEATURES are flagged ONFI-compliant because of their name. This
is not accurate as non-ONFI NAND chips support it and use it.
Rename the hooks and helpers to remove the "onfi" prefix.

Files have been moved in the NAND subsystem to reflect the different
flavors of NAND devices.
Raw/Parallel NAND devices have been moved to a "raw" subdirectory to
make the difference with OneNAND and SPI NAND for instance. So adjust
the Kconfig entry to clarify things.

The blackfin architecture is getting removed, so this driver has

With the move to ->exec_op() the driver should now support ONFI

Now that the driver is using ->exec_op(), remove the old

This reworks the driver to make use of ->exec_op() callback. The
command sequencer of the VF610 NFC aligns well with the new ops
interface.
The operations are translated to a NFC command code while filling
the necessary registers. Instead of using the special status and
read ID command codes (which require to read status/ID from
special registers instead of the regular data area) the driver
now now uses the main data buffer for all commands. This
simplifies the driver as no special casing is needed.
For control data (status byte, id bytes and parameter page) the
driver needs to reverse byte order for little endian CPUs since
the controller seems to store the bytes in big endian order in
the data buffer.
The current state seems to pass MTD tests on a Colibri VF61.

This file can not be built independently any more. We would have to
bring in more to resolve mtd_to_nand(mtd)->ecc.size, for example.
It is difficult to notice a breakage since nobody compiles this mode.
It is not worth fixing or maintaining in my opinion. Remove.

Using pr_<loglevel>() is more concise than printk(KERN_<LOGLEVEL>).
Replace printks having a log level with the appropriate pr_*() macros.
Define pr_fmt() and remove other additional macros from the replaced
printks.

Remove the deprecated ->cmd_ctrl() implementation to use ->exec_op() in
the fsmc_nand driver.
Implement the ->select_chip() hook to avoid having to support the hack
from the core that send a NAND_CMD_NONE with NAND_NCE to signal a
deassertion of nCE.
Also get rid of the last references to ->IO_ADDR_[R|W] that are not used
anymore.

Remove the use of IO_ADDR_[R|W] in the fsmc_nand driver. Instead, use a
pointer to the control registers to avoid doing several arithmetic
operations (including a multiplication) each time a control register is
read or written.
All references to IO_ADDR_[R|W] are not entirely removed from the driver
as, at this time, these values are needed by the NAND core in the
default ->read/write_byte/word() hooks. These references will be
entirely removed when switching to ->exec_op(), that does not make use
of these hooks anymore.
