When creating the next chain of directory entries, (1) add the position
of next entry to the current sector, and then (2) update the sector of
next entry. If the power is turned off between (1) and (2), the next
entry will not be found, and the chain of directory entries will break.
It causes the SmartFS file system corruption, and we will not be able
to add files.
To avoid this issue, in checking the filesystem by smart_fsck_directory,
if the sector of next entry does not exist, update the sector of
directory entry to invalidate the field of next entry.

This change reflects that the geometry isn't related to the largest
allocatable unit on the platform.
Calls to read and write block devices are also affected and have
been updated.
If size_t != uint32_t, this can give a build error:

arch/z80/src/ez80/ez80_spi.c: Do not configure SPI chip select pin. It is not used by the driver and configuring it just clobbers other usage of that pin. Add some additional debug outputs; correct some exiting debug outputs.
drivers/mtd/w25.c: Add some debug output.
boards/z80/ez80/z20x/src/ez80_w25.c: Correct SPI bus number used in initialization. Only SPI1 is supported.
arch/z80/src/ez80/ez80_timerisr.c: Some initial timer configuration fixes.
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.
* Simplify EINTR/ECANCEL error handling
1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx
* Unify the void cast usage
1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro
Driver update
* drivers/mtd/Make.defs: Add MTD driver for QuadSPI-based Winbond NOR FLASH
* stm32l4/stm32l4_qspi.c: the "QSPI_DMA_PRIO" has been defined above
