Here is the third part of the unification time printing in the kernel.
This time for struct timespec64. The first patch brings a support
into printf() implementation (test cases and documentation update
included) followed by the treewide conversion of the current users.

Petr, we got like more than a half being Acked, I think if you are okay
with this, the patches that have been tagged can be applied.

Note, not everything was compile-tested. Kunit test has been passed, though.

Changelog v3:
- fixed a compilation issue with fnic (LKP), also satisfied checkpatch
- collected more tags

Petr, I have not renamed 'p' to 'n' due to much of rework and
noise introduction for the changes that has been reviewed.
However, I addressed the documentation issues.

v2: <20251111122735.880607-1-andriy.shevchenko@linux.intel.com>

Changelog v2:
- dropped wrong patches (Hans, Takashi)
- fixed most of the checkpatch warnings (fdo CI, media CI)
- collected tags

v1: <20251110184727.666591-1-andriy.shevchenko@linux.intel.com>
