* [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][hpm6300evk] Trim trailing blank line * [bsp][hpm6750evk] Trim trailing blank line * [bsp][hpm6750evk2] 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
