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 error handling in smartfs mtd driver
Add error handling in relocate sector.
drivers: mtd: smart: Fix initialize sector sequence value in smartfs
Fix initialization of sequence value into sector header and also avoid
unaligned memory access when CONFIG_MTD_SMART_ENABLE_CRC=n.
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.
Misc changes made following recommendatinos of tools/nxstyle.

drivers/mtd/w25qxxxjv.c: Add QSPI-based Winbond NOR FLASH driver
drivers/mtd/Kconfig: include w25qxxxjv mtd driver to menuconfig
mtd/mtd.h: add function prototype of w25qxxxjv_initialize
- Fix for mx25rxx driver as it does not work properly
- Add mx25rxx memory chip & smartfs support in b-l475e-iot01a/nsh config
- Update smartfs smart_scan() function
1. Configurable option to use named config items instead of enumerated ID/Instance numbers.
2. Ability to iterate through the existing configdata items in the /dev/config device.
3. Ability to "unset" a configdata item.
4. Ability to perform "flash_eraseall" on the /dev/config device.
up_assert: Assertion failed at file:rwbuffer.c line: 643
that can happen with the following configuration:
CONFIG_FTL_WRITEBUFFER=y
CONFIG_DRVR_WRITEBUFFER=y
# CONFIG_FS_WRITABLE is not set
These problems are caused by CONFIG variable differences between the buffer layers. TODO: This is not a perfect solution. readahead support has similar issues.
