fs_getfilep()/fs_putfilep() were renamed to file_get()/file_put().
The PTP clock paths still used the old names, breaking the PTP_CLOCK build.

Now that time_t is unconditionally 64-bit (signed int64_t) and the
struct timespec fields tv_sec / tv_nsec are wide enough on their own,
the explicit (uint64_t)/(int64_t)/(int) casts that used to guard the
multiplications and subtractions in *_us / *_ms / *_ns helpers are no
longer needed. Drop them to keep the timekeeping math readable and
consistent with the previous sclock_t/time_t cleanup.
In the same spirit, this commit also:
* Normalises the printf-style format specifiers and casts used to
print tv_sec / tv_nsec / tv_usec values across arch/, drivers/,
fs/, sched/ and libs/. The prior code was a mix of
"%d"/"%u"/"%ld"/"%lu"/"%lld"/PRIu32/PRIu64 with matching
(int)/(unsigned long)/(long long)/PRIu* casts; some formats
truncated time_t on 32-bit hosts, others mismatched signedness or
width. Replace all such cases with the portable POSIX-recommended
forms:
- tv_sec (time_t, signed, impl-defined width) -> %jd + (intmax_t)
- tv_nsec (long, signed) -> %ld (no cast)
- tv_usec (suseconds_t / long) -> %ld (no cast)
Add #include <stdint.h> where required.
* Drops a few stale `(FAR const time_t *)&ts.tv_sec` casts and
related `(FAR struct tm *)` / `(const time_t *)` casts in
gmtime_r() / localtime_r() / gmtime() callers; ts.tv_sec is plain
time_t now and the casts only obscured the type.
* Fixes one overflow in fs/procfs/fs_procfscritmon.c where
all_time.tv_sec * 1000000 could overflow on 32-bit time_t before
being multiplied again; cast to uint64_t at the start.
No behavioural change.

debug.h is a NuttX-specific, non-POSIX header. Placing it in the
top-level include/ directory creates naming conflicts with external
projects that define their own debug.h.
This commit moves the canonical header to include/nuttx/debug.h,
following the NuttX convention for non-POSIX/non-standard headers,
and updates all in-tree references.
A backward-compatibility shim is left at include/debug.h that
emits a deprecation #warning and re-includes <nuttx/debug.h>,
allowing out-of-tree code to continue building while migrating.

This patch extends CLOCKFD support to clock_getres(), allowing
applications to query the resolution of PTP clocks through file
descriptors using the standard POSIX clock API.
Key changes include:
1. Move clock_getres() from libc to kernel:
- Relocated from libs/libc/sched/clock_getres.c to sched/clock/
- Enables direct kernel-level file descriptor handling
- Maintains POSIX compliance while adding CLOCKFD support
2. CLOCKFD support in clock_getres():
- Detects CLOCKFD-encoded clockids using CLOCKFD_TO_FD() check
- Extracts file descriptor from clockid parameter
- Validates file descriptor through fs_getfilep()
- Issues PTP_CLOCK_GETRES ioctl to query clock resolution
3. PTP clock resolution query:
- Retrieves resolution from PTP clock device via ioctl
- Returns nanosecond-precision timing resolution
- Enables applications to determine clock accuracy capabilities
- Falls back to standard clock resolution for non-CLOCKFD clockids
4. Error handling:
- Returns EINVAL for invalid CLOCKFD file descriptors
- Properly manages file reference counting with fs_putfilep()
- Maintains backward compatibility with existing clock types
5. Build system updates:
- Updated libs/libc/sched/CMakeLists.txt and Make.defs
- Updated sched/clock/CMakeLists.txt to include clock_getres.c
- Ensures proper compilation in kernel context
Usage example:
int fd = open("/dev/ptp0", O_RDONLY);
struct timespec res;
clock_getres(CLOCKFD(fd), &res); /* Query PTP clock resolution */
printf("Resolution: %ld.%09ld sec\n", res.tv_sec, res.tv_nsec);
close(fd);
This completes the basic POSIX clock API support for dynamic PTP clocks,
providing applications with comprehensive clock information access.

here is the reason:
1.clock_systime_timespec(core function) always exist regardless the setting
2.CLOCK_MONOTONIC is a foundamental clock type required by many places
