If a existing file is opened with truncate mode e.g. fopen(file, "w+"),
the file size will be incorrect after writing any data to the file.
Before writing to the first sector, the reading is performed again.
As a result, it makes an invalid file size. When a sector buffer is used,
it must also write to the first sector.
and implement all status related change function. the individual
file system change will provide in other upcoming patchset.

If a existing file is opened with overwriting mode e.g. fopen(file, "w+"),
the file size will be incorrect after writing any data to the file.
This bug is caused by previous commit 10903b5, and its changes should be
limited to only O_APPEND mode.

fs: smartfs: Fix over capacity write
When the remaining capacity of flash is one sector, if a new root
directory is created by file open, then the root directory's chain is
broken and it causes to SmartFS filesystem crash. Once this fatal
problem occurs, it's impossible to recover even if the system reboot.
Fix it by finally update link of root directory.
fs: smartfs: Fix buffer overrun
fs: smartfs: Fix uninitialized variable warnings

boards: cxd56xx: Update spresense board.h
- Fix PMIC assignment
- Add specific pin configurations for spresense
- Remove unnecessary definitions
arch: cxd56xx: Add ITM syslog init at startup

* 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
fs/smartfs: Add logic needed to ftruncate to shrink a file to any arbitrary size.
fs/smartfs: Repartition some functionality to better fit in new ftruncate features.
fs/nxffs: Add partial implementation of the truncate method: It extend files, but cannot yet shrink them.
fs/smartfs: Add partial implementation of the truncate method: It extend files, but cannot yet shrink them.
fs/fat: Add partial implementation of the truncate method: It extend files, but no yet shrink them.
fs/nfs: Add support for the truncate method to the NFS file system.
fs: Add truncate() support for userfs
fs/unionfs: Add truncate() support to the unionfs
fs/tmpfs: Add ftruncate() support to tmpfs
syscall/: Add system call support for ftruncate()
net/route: Adding ftruncate() support eliminates an issue in file-based routing table management.
fs: Add basic framework to support truncate() and ftruncate(). The infrastructure is complete. Now, however, the actual implementation of ftruncate() will have to be done for each file system.
