add an MTD driver for the Macronix MX25UW25645G Octal SPI NOR flash.
Extend the QSPI transfer descriptors with octal and DTR flags so
controller lower halves can issue OPI transactions.

Add QSPI mode to the GD25 MTD driver alongside the existing SPI path.
When CONFIG_GD25_QSPI is selected, sector erase, chip erase, byte read,
page write, and byte write all use the QSPI command/memory interfaces
instead of SPI. Reads use the quad I/O fast-read command (1-4-4) and
writes use the quad page-program command (1-1-4) via QSPIMEM_QUADDATA.
A new Kconfig option enables the QE bit in SR2 at initialisation so the
quad I/O pins are active.

This removes the DEBUGASSERT in ftl_initialize_by_path. Instead, check
compile time that FTL is enabled in case some of the drivers implement
the isbad and markbad functions.
Also select the FTL_BBM for those drivers as they require it.

Bad block management and the logical->physical mapping is only needed
with raw NAND type memories, so we can compile that in conditionally,
saving ~600 bytes of flash on a 32-bit arm when NAND is not used.

We have added a defconfig configuration to set the page size of the flash.
According to the CFI protocol, the flash supports a single write operation
with a data volume ranging from byte size up to the maximum number of bytes.
However, the MTD device structure requires defining a page size, which serves
as the minimum write unit of the flash. Hence, this configuration is introduced.
Any page size within the range of 1 to the maximum number of bytes is considered
valid.

Add MTD driver for Winbond W25N series SPI NAND flash.
Currently supports W25N01GV (1Gbit/128MB).
Features:
- Standard SPI interface with configurable frequency (up to 104 MHz)
- Hardware ECC enabled by default
- Block erase with sleep-based wait (releases SPI bus)
- Page read/write with busy-wait for fast operations
Limitations:
- No bad block management (BBM). Factory bad blocks and runtime bad
blocks are not tracked.
- No bad block table (BBT) scanning at initialization.
- No Quad SPI support (standard SPI only).
- No access to spare area (64 bytes/page) or OTP region.
Tested using:
- Board with STM32H743
- W25N01GV on SPI at 96 MHz with DMA enabled
- Flash mounted using littlefs
- Tested using sdbench:
- Sequential write speed of 1760 KB/s
- Sequential read speed of 4900 KB/s

In order to reduce code duplication, use the eeprom/spi_xx25xx
driver within mtd/at25ee.
The eeprom/xxx.h includes have been merged into eeprom/eeprom.h, to
provide a common include file like mtd/mtd.h.

This commit adds SPI_SETDELAY interface if CONFIG_SPI_DELAY_CONTROL
option is set. This allows to set custom delay between SPI transfers,
chip selects and so on.
Default values are set to 0. W25 SPI NOR flash works with them and
I haven't found any other values in the datasheet.

NVBLK provides a block device that operates on top of a non volatile
memory (as a mtd device) that enables wear levelling for non volatile
memory. It's operation is similar to the dhara wear levelling library,
but nvblk is meant to be used on smaller (nor, mram, rram) memory.
I am also the author and maintainer of the nvblk library.
A block device can be created during startup by using:
```
nvblk_initialize(0, mtd, CONFIG_MTD_NVBLK_DEFAULT_LBS,
CONFIG_MTD_NVBLK_DEFAULT_IOBS,
CONFIG_MTD_NVBLK_DEFAULT_SPEB);
```
and a fat filesystem on top of this as:
```
nsh> mkfatfs /dev/mtdblock0
nsh> mount -t vfat /dev/mtdblock0 /mnt
```
this fat filesystem can then be used:
```
nsh> echo "test" > /mnt/test.txt
nsh> cat test.txt
test
nsh>
```

This commit does two things:
1. First, it reorganizes the driver Kconfig files so that each is self contained. Before, a part of the driver configuration was in drivers/Kconfig and the rest was in in drivers/xyz/Konfig. Now, all of the driver configuration is consolitated in the latter.
2. Second, this commit correct numerous serious errors introduced in a previous reorganization of the driver Kconfig files. This was first noted by Nicholas Chin in PR270 for the case of the drivers/i2c/Kconfig but some examination indicates that the error was introduced into several other Kconfig files as well.
The nature of the introduced error was basically this:
- Nothing must intervene between the menuconfig selection and the following conditional configuration otpions.
- A previous PR erroneously introduced unconditional options between the menuconfig and the following confditional logic, thus corrupting the driver menus.
This error was easy to make because the driver Kconfig files were not well modularized. Making them fully self-contained should eliminate this kind of error in the future.

drivers: mtd: smart: Add smartfs fsck feature
Support fsck to check and repair the smartfs file system. If the power
loss occurs during writing into the flash, the dead space are created
in flash after the next power cycle. To avoid this problem, introduce
fsck and keep the consistency of file system in initializing smartfs.

drivers: mtd: smart: Fix duplicate sector selection in SmartFS
Add care for 16-bit sequence without CRC.
drivers: mtd: smart: Check CRC of duplicate sectors
In the illegal case by power-loss, when the multiple logical sectors are
duplicated, we compare the sequence number of each sector and select the newer
sector. Just in case, add CRC check for the newer sector. If the newer sector
has CRC error, then we use the older sector.
drivers: mtd: smart: SPI-Flash recovery from the initial error state
The FLASH may be not erased in the initial delivery state.
Just in case for the recovery of this fatal situation,
after once erasing the sector, return the sector as a free sector.

drivers: mtd: smart: Fix initialize sector sequence value in smartfs
Fix initialization of sequence value into sector header and also avoid

drivers: mtd: smart: Fix handling of duplicate sector in smartfs
In smartfs scan, if duplicate logical sector is found on the device,
then smartfs selects the winner sector by comparing sequence number,
and the loser sector is soon released. Fix a bug this loser sector
is registered into logical-to-physical sector mapping table.
