更新国民技术BSP架构，添加N32H7xx系列BSP

修改clang_format-ignore文件,根据反馈修改n32h7xxx/libraries/N32_Drivers/nano/*下的文件格式，修改n32h7xxx/n32/n32hxxx/n32h760zil7-stb/applications/main.c文件，区别处理Nano下头文件包含

将N32 BSP的.clang-format-ignore文件放入libraries同级目录

忽略库文件格式检查

[components][clock_time] Refactor time subsystem around clock_time (#11111)

* [components][clock_time] Refactor time subsystem around clock_time

Introduce the clock_time core with clock source/event separation, high-resolution scheduling, and boot-time helpers, plus clock_timer adapters for timer peripherals.

Remove legacy ktime/cputime/hwtimer implementations and migrate arch and BSP time paths to the new subsystem while keeping POSIX time integration functional.

Update drivers, Kconfig/SConscript wiring, documentation, and tests; add clock_time overview docs and align naming to clock_boottime/clock_hrtimer/clock_timer.

* [components][clock_time] Use BSP-provided clock timer frequency on riscv64

* [risc-v] Use runtime clock timer frequency for tick and delays

* [bsp] Add clock timer frequency hooks for riscv64 boards

* [bsp] Update Renesas RA driver doc clock_timer link

* [bsp] Sync zynqmp-r5-axu4ev rtconfig after config refresh

* [bsp][rk3500] Update rk3500 clock configuration

* [bsp][hpmicro] Add rt_hw_us_delay hook and update board delays

* [bsp][stm32l496-st-nucleo] enable clock_time for hwtimer sample in ci

* [bsp][hpmicro] Fix rtconfig include scope for hpm6750evk

Move rtconfig.h include outside the ENET_MULTIPLE_PORT guard for hpm6750evk and hpm6750evk2 so configuration macros are available regardless of ENET settings.

* [bsp][raspi3] select clock time for systimer

* [bsp][hpm5300evk] Trim trailing blank line

* [bsp][hpm5301evklite] Trim trailing blank line

* [bsp][hpm5e00evk] Trim trailing blank line

* [bsp][hpm6200evk] Trim trailing blank line

* [bsp][hpm6750evkmini] Trim trailing blank line

* [bsp][hpm6800evk] Trim trailing blank line

* [bsp][hpm6e00evk] Trim trailing blank line

* [bsp][nxp] switch lpc178x to gcc and remove mcx timer source

* [bsp][stm32] fix the CONFIG_RT_USING_CLOCK_TIME issue.

* [docs][clock_time] add clock time documentation

* [docs][clock_time] Update clock time subsystem documentation

- Update device driver index to use correct page reference
- Clarify upper layer responsibilities in architecture overview
- Update README to describe POSIX/libc, Soft RTC, and device driver usage
- Refine architecture diagram with improved layout and color scheme
- Remove obsolete clock_timer.md file

* [kernel][utest] Trim trailing space

* [clock_time] Fix hrtimer wrap handling

* [clock_time] fix the static rt_inline issue

* [clock_time] fix the rt_clock_hrtimer_control result issue

fix[dfs_v1]: prevent vnode ref underflow and double release on close/fd release

feat[STM32][CAN]: drain RX FIFO frames in ISR with a bounded limit to reduce overruns

- Add CAN_ISR_DRAIN_LIMIT (default 3) to cap ISR work
- Drain multiple frames per RX0/RX1 interrupt to reduce FIFO FULL/OVERRUN

docs(can): improve dev_can.h docs for batched RX example

fix[STM32][RTC]: Compute tv_usec from SecondFraction/SubSeconds and skip during shift pending

Use the generic SecondFraction/SubSeconds formula when SSR/PRER are available.
If SHPF is present and a shift is pending, keep tv_usec at 0.
Platforms without SSR/PRER (e.g. F1) default to 0.
