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.
* [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.

[tools][cmake] fix type handling when generating CMake targets
[Root Cause]
Unexpected macro definition types during `scons --target=cmake`
could trigger a TypeError and abort CMakeLists.txt generation.
[Solution]
Add support for handling different macro definition types.
[Affect Area]
cmake.py
[Test Suggestion]
Run `scons --target=cmake` and verify CMakeLists.txt is generated
successfully with different macro definition formats.
Problem:
When enumerating device tree nodes, platform bus and native buses (I2C/SPI)
may create duplicate devices for the same OFW node, causing cross-bus conflicts.
This triggers assertion failure '(dev->bus != new_bus)' in
rt_bus_reload_driver_device() during boot on minimal DM-enabled systems.
Root Cause:
1. Platform bus tries to reload devices that already belong to other buses
by calling rt_bus_reload_driver_device(dev->bus, dev), which violates
the API contract (requires dev->bus != new_bus).
2. Native buses (I2C/SPI) do not mark OFW nodes as occupied, so platform
bus creates duplicate platform devices for I2C/SPI client nodes.
Solution:
1. components/drivers/core/platform_ofw.c: Return RT_EOK when np->dev exists,
letting the native bus handle device lifecycle instead of cross-bus reload.
2. components/drivers/i2c/dev_i2c_bus.c: Mark i2c_client_np->dev during scan
to prevent platform bus from duplicating I2C client devices.
3. components/drivers/spi/dev_spi_bus.c: Mark spi_dev_np->dev during scan
to prevent platform bus from duplicating SPI devices.
Tested on Spacemit K1 RISC-V platform with minimal DM configuration.
