[RFC PATCH v2 0/5] cmd: fuse: Introduce fuse writebuff sub-system and clean up

[Harsha Vardhan V M]

This patch series introduces the fuse writebuff sub-system command and
makes improvements to the existing fuse implementation by removing the
custom string functions. The patches are required to be applied in
sequence.

The series consists of the following changes:
Patch 1 removes custom string functions and replaces them with standard
string functions.
Patch 2 introduces fuse.rst documentation for fuse commands.
Patch 3 introduces the fuse writebuff sub-system command, allowing to
write a structured buffer in memory to fuses, and implementing the
necessary function calls.
Patch 4 enables the fuse sub-system in the K3 platform.
Patch 5 updates the fuse.rst documentation to include details about the
new fuse writebuff command.

These changes aim to improve the fuse sub-system by the removal of
custom string functions and the addition of the fuse writebuff
command improves fuse programming workflows by allowing to write a
structured buffer in memory to efuses.

Changes in v2:
  1.Convert doc/README.fuse to doc/usage/cmd/fuse.rst as patch #2,
  as requested by trini at konsulko.com.
  2.Add fuse writebuff documentation in fuse.rst in the final patch.
