* [dm][dma] update DMA interface
Extend DMA mapping to honor OFW dma-ranges even
when no reserved memory pool is present,
and add PCI host-bridge DMA-region translation for PCI devices.
Prefer 32-bit-addressable allocations for translated devices,
improve pool allocation fallbacks and synchronization,
and establish a linear mapping for installed DMA pools when possible.

* [dm][dma] fixup PL330 work flow
Fix PL330 channel allocation so device-tree cells
select peripheral request lines rather than execution channels.
Generate proper peripheral DMA microcode using DMAWFP, DMALDP, DMASTP, and DMAFLUSHP,
encode burst lengths correctly,
honor transfer direction and non-secure attributes,
and allocate microcode from DMA-coherent memory.

* [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.

1.Add the necessary function declarations for SMP enablement and implement the corresponding
functionalities, including rt_hw_secondary_cpu_up, secondary_cpu_entry, rt_hw_local_irq_disable,
rt_hw_local_irq_enable, rt_hw_secondary_cpu_idle_exec, rt_hw_spin_lock_init, rt_hw_spin_lock,
rt_hw_spin_unlock, rt_hw_ipi_send, rt_hw_interrupt_set_priority, rt_hw_interrupt_get_priority,
rt_hw_ipi_init, rt_hw_ipi_handler_install, and rt_hw_ipi_handler.
2.In the two functions (rt_hw_context_switch_to and rt_hw_context_switch) in context_gcc.S,
add a call to rt_cpus_lock_status_restore to update the scheduler information.
3.If the MMU is enabled, use the .percpu section and record different hartids by configuring
special page tables; if the MMU is not enabled, record them directly in the satp register.
Additionally, add dynamic startup based on core configuration.The .percpu section is only used
when both ARCH_MM_MMU and RT_USING_SMP are enabled. However, there is a certain amount of space
waste since no macro guard is added for it in the link script currently.
4.The physical memory of QEMU started in CI is 128MB, so RT_HW_PAGE_END is modified from the
original +256MB to +128MB. Modify the SConscript file under the common64 directory to include
common/atomic_riscv.c in the compilation process.

The context_gcc.S file was incorrectly marked as cortex-m4 in both the
doxygen comment and .cpu directive, while the IAR and KEIL versions
correctly specify cortex-m33. This file uses ARMv8-M specific features
(PSPLIM register, TrustZone support) that are not available in Cortex-M4.
Changes:
- Update doxygen group from cortex-m4 to cortex-m33
- Change .cpu directive from cortex-m4 to cortex-m33
